The Race to Run Chicago
Money, machines and the fight for City Hall, and the one attack that could knock each candidate out
By the F'nAround reporting desk | Chicago | October 24, 2026
A note on sourcing before the story begins. Filing for the February ballot closes on October 26, and petition challenges only open on October 27, so as of this writing there is no certified ballot. Signature totals below are the totals campaigns filed, not totals the Board of Election Commissioners has sustained. Fundraising figures are drawn from the most recent quarterly disclosure reports available for the field. Prediction-market prices are reported as market snapshots, not as polls, and are flagged where the market is thin. Allegations that have not been adjudicated are identified as allegations throughout. Findings, verdicts, settlements and enacted laws are identified as such.
Nobody wins this race in February. They survive it.
CHICAGO - The next mayor of Chicago will almost certainly not be chosen on Election Day. With a field that includes an incumbent mayor, a sitting secretary of state, a former state comptroller, a sitting congressman and a bench of aldermanic, activist and perennial candidates behind them, the February 23, 2027 municipal election is structured less like a coronation than like a cut. Under Chicago's nonpartisan system, a candidate who clears 50 percent of the vote wins outright. Nobody in a field this size, with this much money moving this early, is polling anywhere near 50 percent. The realistic prize in February is a ticket to the April 6 runoff, and the realistic question hanging over every campaign is simpler and crueler: who finishes second, and who gets exposed on the way there?
The winner takes the oath on May 17, 2027, and inherits a city that is simultaneously a national symbol in arguments about crime, migration, transit and progressive governance, and a balance sheet under genuine strain. Chicago's proposed fiscal year 2027 budget totals $17.6 billion, built to close a projected gap of $882.4 million. How the current administration proposes to close that gap, through revived corporate head tax proposals and an expanded lease tax on cloud computing and software that critics have branded a cloud tax, has already triggered open revolt among aldermen who would normally be counted as allies. Whoever wins this race does not get a honeymoon. They get that budget, that council and that argument, on day one.
That is the stakes frame. What follows is the race itself: the strange constitutional side door opened by the frontrunner's current job, the signatures that got everyone to the starting line, the money that separates a campaign from a candidacy, the way Chicago actually votes when it is choosing a mayor, and the records on crime, lawsuits, cannabis and casinos that each candidate will spend the winter trying to outrun. A second section then does the less polite work. It takes each serious candidate and states, plainly and on the record, the weakest point in their candidacy: the attack a competent opponent would build a closing argument around, and the votes, ties and support behind it that make the attack stick.
The Secretary of State problem: a second election hiding inside the first
Start with the oddity at the center of the race. Alexi Giannoulias is not a former officeholder looking for a comeback or an outsider looking for a break. He is Illinois' sitting Secretary of State, one of the most powerful and patronage-rich offices in state government, the office that runs driver services, the state library system, the corporation database and a workforce spread across every corner of Illinois. He is asking Chicago voters to hire him for a new job while he still holds the old one, and that single fact creates the most unusual structural question of the 2027 cycle: what happens to the Secretary of State's office if he wins both races?
The sequence matters, and it is worth walking through slowly, because opponents will not walk through it slowly at all. Giannoulias is on the ballot for re-election as Secretary of State in November 2026 and for mayor in February 2027. If he wins both, he cannot hold both. The mayoral oath is scheduled for May 17, 2027, and he would have to resign the Secretary of State's office before taking it. A resignation by a statewide constitutional officer creates a vacancy that the governor fills by appointment. In plain terms, a vote for Giannoulias for mayor in February is also, in effect, a decision to hand Governor J.B. Pritzker the power to choose the next Secretary of State, a statewide officer Chicago voters and Illinois voters alike elected Giannoulias himself to be, without an election at the moment of handover.
How long the appointee would serve before facing voters is the part lawyers will argue about and opponents will not wait for. Under the state's vacancy framework, appointments to fill a statewide vacancy run until an election can be held, and the timing rule commonly applied turns on how much of the term remains, with a threshold in the region of 28 months separating an appointment that runs to the next general election from one that triggers a special election. Applied to a May 2027 resignation, the analysis developed in the research behind this article points toward a special election in November 2028. That conclusion should be read honestly for what it is: a derived reading of the vacancy provisions, not settled precedent tested on these exact facts, because Illinois has not run this precise play, a statewide officer resigning mid-term to take a mayoral oath in Chicago, in modern memory. What is not in dispute is the core of it. For a period measured in many months and plausibly well over a year, the Secretary of State of Illinois would be a person no voter chose for the job.
Giannoulias' campaign can answer, and has the raw material to answer, that this is how vacancy law works for every office in the state, that governors appointing successors is a feature of the Illinois Constitution rather than a scheme anyone invented for this race, and that voters are fully capable of weighing a known process when they vote. All of that is true. It is also, as the knockout section below argues at length, not the point. The point is what the arrangement looks like from a kitchen table in Pilsen or a barbershop in Chatham: the best-funded candidate in the race asking to be promoted, and the price of the promotion being that his old job, an office famous in Illinois history for patronage, gets filled by appointment in Springfield. In a city whose politics were built by machines and whose voters have spent a decade punishing anything that smells like one, that is not a legal problem. It is a story problem, and story problems are the kind that lose runoffs.
Signatures: the first campaign is fought in the cold, on clipboards
Before any of these candidates could spend a dollar on television, they had to survive the least televised and most Chicago part of the process: petitions. A mayoral candidate needs 12,500 valid signatures to appear on the ballot, and the operative word is valid. Seasoned campaigns file two to three times the minimum because Chicago petition challenges are a blood sport with a long pedigree: signatures are struck for signers who are not registered at the address given, for circulators who mishandle their sheets, for handwriting that does not match the voter file. Filing closes on October 26, 2026, and challenges open the next day, which means every total in this race should be read as a claim awaiting cross-examination rather than as a result.
Read that way, the signature phase still tells a real story about organization. The best-funded and best-staffed operations, the Giannoulias and Mendoza campaigns in particular, filed totals comfortably in excess of the threshold, the kind of cushions that signal paid circulator operations layered on top of ward-level volunteer networks. The incumbent's operation filed from the position of an office that has spent four years building lists. The trailing and first-time candidates filed closer to the line, which is precisely where challenges bite: a campaign that files at 14,000 signatures does not need to lose many arguments before it is below 12,500 and off the ballot entirely. Until the Board rules on the challenges, the honest sentence is the narrow one. These candidates filed. Whether all of them will be voted on is a question the process, not the campaigns, will answer in the coming weeks.
Money: one campaign is playing a different sport
If signatures are the entry fee, money is the race, and by that measure this race has a frontrunner and then it has everyone else. Through the third-quarter disclosure reports, Giannoulias reported approximately $19.15 million. Mayor Brandon Johnson reported approximately $379,471. Put those two numbers next to each other and the shape of the contest changes. That is not a fundraising lead. That is a fifty-to-one cash disparity between the challenger and the incumbent mayor of the third-largest city in the United States, and Johnson's reported balance declined quarter over quarter rather than recovering. Susana Mendoza, whose years as state comptroller and city clerk gave her donor relationships across the business and labor worlds, sits in the credible middle tier of the money race. Congressman Mike Quigley brings a federal fundraising network built over years in Washington. Behind them, the rest of the field, including Alderman George Cardenas, Dr. Willie Wilson, Paul Vallas-era veterans of past cycles where applicable, and activist and community candidates such as those building from church, block club and independent political organization networks, are running campaigns in which a single Giannoulias television week could exceed their entire budgets.
Money in Chicago mayoral races does not buy votes directly, and the city's recent history is full of well-funded losers. What it buys is survival through the winter: the staff to defend petitions, the polling to know which wards are actually moving, the mail and digital programs to define an opponent before that opponent can afford to define themselves, and, above all, the ability to still be standing in March when the runoff electorate, smaller, older and more homeowner-heavy than the February electorate, makes its decision. A candidate with $379,000 in October does not have a message problem. They have a calendar problem, because the calendar between now and February is denominated in media buys they cannot make.
The donor coalitions behind the money matter as much as the totals, because in Chicago, who funds you is a preview of who you will owe. Giannoulias' coalition draws heavily on the business, legal and real estate donor class that has historically funded statewide Democratic campaigns in Illinois, supplemented by labor support that reflects his statewide relationships, most visibly in the split described below. Johnson's coalition remains rooted in the Chicago Teachers Union, whose financial and field support powered his 2023 victory, alongside progressive organizations and smaller-dollar networks. Mendoza's support bridges the business community and building-trades and public-sector labor relationships accumulated over two statewide terms. Quigley's reflects the North Side and suburban-adjacent Democratic establishment and his long congressional incumbency. Each of those coalitions is also, read from the other side, an attack surface, and the knockout section treats them that way.
Polls say a race. A betting market says a rout. Believe the polls.
Two numbers about this race have circulated widely, and they do not agree with each other, which is itself the most useful information in this section. On Kalshi, the regulated prediction market where traders buy and sell contracts on election outcomes, Giannoulias has been priced at roughly 74 percent to win the mayoralty. In a NORC survey of the actual electorate, Giannoulias stood at roughly 25 percent support, with Johnson at roughly 14 percent and the remainder of the field dividing the rest alongside a large undecided bloc. A candidate cannot simultaneously be a three-in-four certainty and the first choice of one voter in four, and the resolution of the contradiction is methodological, not mysterious.
Prediction markets price a probability of eventually winning, including through a runoff, and they aggregate the beliefs of a small, self-selected pool of traders who are often pricing momentum, fundraising coverage and conventional wisdom as much as Chicago ward politics. In a thin market, a modest amount of money can move a price dramatically, and the 74 percent figure should be treated as an unverified snapshot of a shallow market rather than as a measurement of the electorate. A survey, whatever its own margins and undecideds, at least asks Chicago voters. What the survey actually describes is the real race: a fragmented plurality contest in which the leader is at a quarter of the vote, the incumbent is in the mid-teens, most voters have not settled, and the runoff pairing is wide open. Anyone who tells you this race is over, in either direction, is selling you a market price as if it were a vote count.
How Chicago votes: the map underneath the money
Chicago does not vote as a city. It votes as fifty wards that behave like fifty small towns with different economies, different racial and ethnic compositions, different relationships to downtown and different memories of the last mayor. The 2023 election that made Brandon Johnson mayor is the essential map. Johnson assembled a coalition anchored on the North and Northwest Side progressive wards, powered by the Chicago Teachers Union's field operation, and carried enough of the South and West Sides, where his runoff opponent Paul Vallas ran strongest on a public-safety message in the bungalow-belt and homeowner wards of the far Southwest and Northwest Sides, to win a runoff that broke almost exactly along the city's argument with itself about crime, schools and policing.
Every 2027 strategy is a variation on reassembling or breaking that map. Giannoulias' path runs through the lakefront and North Side wards where statewide Democrats run strongest, plus the downtown and near-loop electorate that responds to a managerial, electability-first pitch, while competing for the Latino wards of the Southwest and Northwest Sides where no 2027 candidate starts with a lock. Mendoza, a daughter of the Southwest Side with deep roots in its Mexican American community and a record of winning citywide and statewide, contests exactly those wards from a stronger starting position, which is why the Giannoulias and Mendoza campaigns are on a collision course for the same voters even though they rarely say each other's names. Quigley's base is the North Side congressional district he has represented for years. Johnson's defense begins with holding the CTU-anchored progressive base and the Black wards of the South and West Sides against challengers arguing that his administration has not delivered safety or stability there. Cardenas speaks to a Southwest Side aldermanic base and a pro-business, public-safety lane. Wilson, who has run citywide before, retains a church-based and South and West Side following that has made him a persistent double-digit factor in past fields.
The labor map cuts across the racial and geographic one, and this cycle it is visibly split. The Chicago Teachers Union remains the incumbent's foundation: the union did not merely endorse Johnson in 2023, it substantially constituted his campaign, and his administration's negotiating posture toward the union is both his base's greatest loyalty and his opponents' favorite exhibit. Service employees and other public-sector unions, whose members experience city government as an employer in a budget crisis rather than as a movement project, have been more open to the challengers, and building-trades support, historically decisive in funding and in turning out the homeowner wards, is contested ground that Mendoza and Giannoulias are both courting. A labor endorsement in Chicago is never just a logo on a mailer. It is precinct workers, phone banks and money, and a split labor movement is one of the clearest signals that the incumbent coalition of 2023 no longer exists as a single thing.
The budget: the race is about a spreadsheet whether candidates like it or not
Strip the speeches away and the FY2027 budget is the campaign document nobody wrote but everybody is running on. A $17.6 billion spending plan carrying an $882.4 million projected gap forces a choice among three unpopular options: raise revenue, cut services, or borrow against the future and let the rating agencies deliver the verdict. The Johnson administration's proposals, reviving a corporate head tax on large employers and expanding the lease tax to cloud services, were framed by the mayor's team as making large corporations pay their share. They were received by a striking number of aldermen, including members who had supported the mayor on other signature fights, as a jobs and competitiveness risk the city could not afford, and the council pushback became a story in itself: an incumbent mayor unable to carry his own revenue plan through his own council heading into his own re-election.
Each challenger has converted that fight into a character argument. To Giannoulias and Mendoza, the budget is evidence of managerial failure, a mayor who fights with his council, his business community and Springfield simultaneously and delivers stalemate. To Johnson's defenders, the same fight is evidence of a mayor willing to tax wealth in a city that has historically balanced its books on fines, fees and property taxes paid by working people. Both readings will appear in runoff advertising almost verbatim. The underlying arithmetic will outlast both: pension obligations, debt service and the structural gap do not care who wins, and the next mayor's first year will be measured against a spreadsheet that has already been published.
Crime, lawsuits, cannabis and casinos: the records that follow them
Public safety remains the issue Chicago voters rank first, and the recent record is genuinely mixed in ways each campaign will slice differently. Johnson dismantled the city's ShotSpotter gunshot-detection contract, a decision his supporters defend on civil-liberties and efficacy grounds and his critics cite whenever response and clearance debates flare. The city continues to pay out large settlements in wrongful-conviction and police-misconduct litigation, including cases in the long shadow of the Reynaldo Guevara scandal, in which dozens of convictions tied to the former detective have been vacated; those settlement figures are adjudicated public facts, approved by the council, and opponents treat every new one as a line item in an argument about the cost of the city's policing history. Johnson's supporters answer, accurately, that the underlying misconduct predates his administration by decades. Both things are true at once, which is why the issue never resolves and never leaves.
Cannabis and gambling, the two vice industries Illinois legalized and Chicago spent years arguing about how to host, run through this race as economic and equity questions. At the state level, Governor Pritzker's effort to regulate intoxicating hemp products was blocked in the legislature in a fight that exposed the split between the licensed cannabis industry, which wanted hemp competitors regulated or banned, and hemp businesses and their legislative allies; Giannoulias' opponents have worked to place him on the Springfield-insider side of every such fight by association with the state establishment that fought it, while his campaign points to his actual office, which licenses businesses and charities rather than setting cannabis policy. That distinction is real and voters will have to decide how much it matters. On casinos, the city's Bally's project and the long fight over video gaming terminals, which pitted the city's casino interests against the VGT industry in Springfield, ruptured relationships between City Hall and the state's gaming stakeholders; Johnson's handling of the casino timeline and the VGT question is part of the business community's broader case that his administration is difficult to deal with, while his defenders note the casino deal itself was inherited from the prior administration. The pattern across all four files, crime, lawsuits, cannabis and casinos, is the same. The underlying decisions are documented. The blame assignment is the campaign.
The rest of the field: eight more declared candidacies
Six candidacies do not make this field. This article profiles 18 declared candidates in all: 14 principal declared candidates, plus 4 further declared lower-tier candidates. Adding 1 pending candidacy, Maria Pappas, and 1 withdrawn candidacy, Liam Stanton, brings the record to 20 candidacies in total. Several of the names beyond the top tier filed signature totals, raised seven-figure sums or carry records that will matter in a runoff argument. What follows is the rest of the declared field, candidate by candidate, on the same terms as the frontrunners: background, signatures filed, money, and the voters each campaign is actually built to reach. Where the public record on a candidate is thin, the entry says so rather than filling the space. Petition filing opened on October 19 and runs through October 26, so a candidate with no filed total in these entries had not reported one as of this writing, and no ballot is certified until the Board of Election Commissioners rules, with certification expected by December 17.
Matt Brewer: the housing chief the mayor removed
Brewer is the candidate this race produced out of a governing fight. A lawyer and partner at Bartlit Beck, with degrees reported from Stanford, Yale and Harvard, he has sat on the Chicago Housing Authority board since 2013, became vice chair in 2021 and became its operating chair last September after Angela Hurlock stepped down from the interim chief executive role. This spring the board voted 7 to 2 to hire Keith Pettigrew as chief executive, and Mayor Johnson removed Brewer as chair, alleging the hiring process flew in the face of open meetings law and transparency rules. Brewer remains a commissioner, and the fight over who controls the authority, the second largest public housing agency in the country, with a budget of about $1 billion serving more than 63,000 families, is still running through the City Council, which has blocked further Johnson nominees. Brewer announced in June with a direct attack on that record: at the authority, he said, he had a front row seat to the dysfunction coming out of City Hall, and Chicago was being offered a false choice about its future. His business interests will follow him into the race: he co-owns The Wieners Circle, the Lincoln Park hot dog stand whose marquee has mocked the mayor, and he helped open and co-owns Grasshopper Club, described in coverage of his candidacy as the city's first Black owned cannabis dispensary. He is also the founder of floChicago, a nonprofit leadership program.
On signatures and money, Brewer filed like a serious candidate and reported like a mid-tier one. He was in line on the first filing day, October 19, and said he submitted over 32,000 signatures, comfortably more than double the 12,500 threshold and enough to enter the lottery for the top spot on the ballot. No cash on hand figure for his committee appeared in the third quarter summaries published on October 16, which is itself information: whatever he has banked, it was not in the published roundup that put seven other campaigns on the board. His voter base is the widest open question in the field. Analysts who rank the field give him the broadest range of outcomes of any challenger: a North Side good government and liberal electorate looking for a competent alternative to both Johnson and Giannoulias, plus Black voters reached through a decade of housing work, is a coalition that could surge late the way the last two winning mayoral coalitions surged. It is also, so far, a coalition described in potential rather than in polling, endorsements or ward organization.
John Kelly: the lobbyist with the second biggest bank account
Kelly has spent 28 years as a City Hall lobbyist, and he is running on the argument that lobbying is the job. His clients over that career have included the Chicago White Sox, the United Center and Bally's, the casino operator whose Chicago casino sits at the center of the city's gambling future, and he runs his own consulting firm. The skills you need to be a successful lobbyist, he told reporters on launching, are exactly the skills you need as mayor, and a mayor with better lobbying skills would be in Springfield getting Chicago its fair share. He says he has de-registered as a city lobbyist for the campaign and would sell his business if he wins, and he points to 28 years without an ethical concern as his answer to the conflict question. His platform is law and order in the plainest terms in the field: more police officers, a transit system riders feel safe on, property taxes stabilized by growing the downtown tax base rather than raising rates. He was among the candidates who signed the University of Chicago Crime Lab public safety pledge this summer.
His numbers are why the rest of the field cannot ignore him. Kelly filed on the first day with an estimated 36,000 to 37,000 signatures, and his third quarter report showed $2.52 million on hand, second only to Giannoulias and ahead of Mendoza, Holberg and the incumbent. That is self reinforcing money: a lobbyist's donor network is a Rolodex of people who give to stay in the room, and analysts expect him to be able to raise millions more and hold a real presence on television and in mailboxes. His voter base is the mirror image of the incumbent's: conservative and moderate Democratic neighborhoods, white ethnic wards on the Northwest and Southwest sides, police and fire households, and, as WBEZ has reported, voters who backed Donald Trump in 2024, a lane his campaign has courted even as he calls himself a Democrat. It is a real base in a fragmented field. It is also a base with an obvious ceiling in a run off in one of the most Democratic big cities in America, which is where his entry in the Knockout File begins.
Joe Holberg: first into the race, still running as the outsider
Holberg was the first candidate in this race, announcing on October 6, 2025, more than a year before the filing window, and his biography is the campaign. He grew up in a financially unstable household, received food stamps early in life, and has described choosing tuition over rent at the University of Michigan and living in his car. He worked as a math teacher on Chicago's West Side and with AmeriCorps, then founded a money management firm, Holberg Financial, in 2015 to teach the financial basics his own education had skipped. The firm, renamed Spring, was acquired by Mariner Wealth Advisors in January 2023, with Holberg becoming a managing director of the financial wellness business built on it. He wrote Rogue Finances in 2017 and has now published his platform as a book, The Holberg Plan, which his campaign bills as the first campaign book published by a Chicago mayoral candidate. The platform is growth arithmetic: restart the economic engine, build at least 100,000 new homes, balance the budget without mortgaging the future, and improve schools. He, too, signed the Crime Lab public safety pledge.
His money is real and his ballot position is not yet documented. Holberg finished the third quarter with $1.06 million on hand and more than $1.35 million raised in total, including over $183,000 in the third quarter, and his campaign claims more than 1,000 volunteers, supporters and donors. Those figures put him fourth in cash in the field, ahead of the incumbent, and they were built without a political machine, which is his core claim on the race. No first day signature total was reported for his campaign when filing opened on October 19, and the window runs through October 26, so his petition cushion will be judged when he files. His voter base is the professional, reform minded electorate: North Side and near Loop voters, education and finance networks from his teaching and start up years, and younger homeowners priced by the housing shortage he has made his signature issue. The weakness is symmetrical to the strength. He has never held elected office, cast a public vote or run a public budget, so there is no voting record for opponents to attack and no governing record for supporters to point to. Everything rests on whether a plan, however detailed, reads as experience.
Lisa Nee: the whistleblower running on broken systems
Dr. Lisa Nee is the field's clearest single story candidate. A lifelong Chicagoan who grew up in Humboldt Park, competed in Division I track at Loyola and worked her way from intensive care nurse to interventional cardiologist, she was working at the Edward Hines Jr. VA Hospital when she raised alarms about failures in patient care, including a backlog of life saving heart tests that had gone unread, putting veterans at risk. She says she was told to stay quiet, refused, faced retaliation and kept escalating, work that fed into federal efforts to strengthen protections for veterans and whistleblowers; she testified before a United States Senate hearing in 2015. In the middle of that fight she was diagnosed with breast cancer and became a survivor. After leaving clinical practice she earned an MBA from Northwestern's Kellogg School of Management and now works as a healthcare and public policy advisor; she led medical teams during the COVID pandemic. Her campaign, launched July 7 under the banner of healing Chicago, generalizes the VA experience into a theory of City Hall: systems fail people, insiders protect the system, and leadership means listening, deciding on data and refusing to stay quiet.
The campaign infrastructure has not caught up with the biography. Nee's third quarter report showed $50,697.51 on hand, roughly the cost of a single modest mailing in a citywide race, and no signature total from her campaign was reported on the first filing day. Her natural base is specific rather than broad: veterans and their advocates, healthcare workers and patients, good government voters who prize independence, and professional voters on the North and Northwest sides who respond to a competence message. That base overlaps heavily with the electorates Quigley, Holberg and Brewer are courting, and she enters that contest with the least money of the group. Her public record is also a thin one for the office she seeks, stated plainly: it is a distinguished clinical and whistleblowing record inside a federal hospital system, with no elected office, no municipal budget and no city agency on it. Whether that reads as purity or as unpreparedness is the whole argument over her candidacy, and it is taken up in the Knockout File.
William Quinlan: the candidate who sued the field
William J. Quinlan, who files and campaigns as Bill Quinlan, is an attorney who entered the race in mid September and immediately made himself the race's legal department. Within days of announcing, he sued Giannoulias, Quigley and Cook County Treasurer Maria Pappas, asking a Cook County court to declare that a 2024 change to Illinois election law bars them from running for re-election to their current offices on November 3 while also running for mayor. The statute at issue, section 10-7 of the Election Code, addresses candidates presented for two or more incompatible offices, and Quinlan's argument is that the new filing calendar, which moved mayoral filing to October 19 to 26, created an overlap that earlier cycles never had. Voters deserve candidates who are all in, he said, not career politicians keeping one seat warm in case the other race does not go their way. Election lawyers quoted at the time called the suit a long shot, and on October 14 Judge Eve M. Reilly dismissed it as not yet ripe for a decision, ruling on timing and expressly not on the merits. Quinlan vowed to appeal and to seek a definitive answer before November 3. The same theory, notably, was not aimed at Cardenas, who holds a county office and a mayoral candidacy at once and was not named as a defendant.
His money carries a question mark that his opponents have noticed. His campaign told reporters in September that it had roughly $600,000 banked and then added another $250,000 in contributions, but trackers of the race noted, repeatedly and without resolution, that no state filing reflecting those totals had appeared, and the third quarter roundup listed his committee at $204,215. That gap is reported here as an unreconciled difference between a campaign claim and a public filing, not as a finding of anything. On signatures, Quinlan took the opposite route from the first day filers: along with Mendoza, he said he would wait and file on the last day, Monday, October 26, which puts his campaign in the lottery for the last spot on the ballot rather than the first. His voter base is the narrowest in the field, good government and anti machine voters who care about the dual office question itself, plus whatever attention a lawsuit against three better known rivals can rent. It is a candidacy built to make one argument. The Knockout File asks what happens to it if the argument loses.
Toni Brooks: the responder building block by block
LaTonia Brooks, who campaigns as Toni Brooks, is a Chicago born United States Army National Guard veteran, a nonprofit founder and executive, and an anti violence organizer. Her campaign language is neighborhood scale by design: rebuilding block by block, reallocating city money toward the blocks that violence hits hardest, a large Citizen Responder volunteer network to stand alongside professional first responders, and a pledge to donate most of a first year mayoral salary to a community fund. She has been interviewed by WTTW and CBS, which is more local television exposure than most first time candidates get, and her biography lets her speak about public safety as service rather than as statistics, the same emotional register Kelly works from the opposite political direction. Beyond that biography and platform, the documented public record is thin, and this entry will not pretend otherwise: no elected office, no voting record, no agency record and no major endorsement has been reported for her campaign.
The thinness extends to the two numbers this article has used to sort the field. No cash on hand figure for Brooks appeared in the third quarter summaries published on October 16, and no signature total from her campaign was reported when filing opened on October 19, with the window open through October 26. Her voter base, on the evidence available, is the network she built herself: South and West Side neighborhood organizations, churches, veterans and anti violence advocates, and voters who want a mayor from the blocks most affected by the issues the frontrunners debate. In an eighteen-candidate declared field that base does not need to be large to be visible. It does need petitions that survive challenge and enough money to be heard once, and neither has been demonstrated in a public filing yet.
Danielle Carter-Walters: the Republican in a nonpartisan race
Danielle Carter-Walters, 52, is a Chicago native, a small business owner and the wife of a retired Chicago police officer. She is best known as a co-founder and vice president of Chicago Flips Red, the organization built to argue that Black and working class Chicagoans are abandoning the Democratic Party, and she is running, as CBS put it on her entry in July, as a Republican among many Democrats. In Chicago's nonpartisan mayoral election there is no party label on the ballot, but there is no hiding a political identity either, and Carter-Walters does not hide hers: she campaigns on public safety and law and order, forensic audits of city spending, accountability with indictments and prison time for corruption, freezing property taxes, and ending Chicago's sanctuary city status. She has taken that message to national conservative media, including Newsmax, and to joint meet and greet events on the South Side with Republican congressional candidates under the Chicago Flips Red banner.
Her documented campaign numbers are, at this stage, the thinnest of any candidate in this section. No cash on hand figure for her campaign appeared in the third quarter summaries published on October 16, and no signature total was reported on the first filing day; her campaign held a petition kick off over the summer and the filing window runs through October 26. Her voter base is the one she and Chicago Flips Red have spent two years assembling in person and online: conservative voters inside a Democratic city, police and first responder families, South Side voters angry about crime, taxes and the migrant response, and a national online audience that follows her content. That audience is real and it donates and shares. Whether it votes in a Chicago municipal election in February, in numbers that survive contact with an eighteen-name ballot, is the unproven step in her campaign, and the party identity that built the audience is also the ceiling opponents will draw around it.
Zoe Ma: the developer running as an independent progressive
Zoe Ma is the last declared candidate into the race and, demographically, the most distinctive. A real estate developer and property manager who immigrated from China and has lived in Chicago for decades, she launched an independent bid in Bronzeville on September 1, seeking, in the coverage of her launch, to become the city's first Chinese American and first Muslim mayor. Election listings also identify her as chair of the Cook County Green Party, which makes her the only candidate in the field carrying a third party leadership role into a nonpartisan race. Her themes are economic: poverty and inequality, budget transparency, property tax reform, affordable housing and a guaranteed income program, a progressive platform run from outside the Democratic organization entirely. Her campaign site is zoemaformayor.com and her base building has run through Bronzeville and South Side community networks rather than through labor, ward or donor structures.
On the sorting numbers, Ma's record is a blank that has to be reported as a blank. No cash on hand figure for her campaign appeared in the third quarter summaries published on October 16, and no signature total was reported on the first filing day, three weeks after her launch, with the window open through October 26. She has no elected office and no voting record, and her public record before September is a real estate and community advocacy record rather than a governmental one. Her voter base is therefore a hypothesis her campaign has to prove: Asian American voters who have never had a mayoral candidate from their community, progressive independents and Green Party networks, Bronzeville and South Side voters drawn to the tax and housing message, and younger voters open to a guaranteed income. Every element of that coalition is plausible. None of it has yet appeared in a poll, a filing or an endorsement list, which is the factual core of her Knockout File entry below.
The lower tier and the pending name: Pappas, Taylor, Maronto, Logalbo and Su
Maria Pappas is the most consequential name not yet formally in this race. Cook County Treasurer since 1998, after eight years as a Cook County commissioner, she has said she plans to run for mayor and is widely expected to announce after the November 2026 elections, in which she is herself seeking re-election as treasurer. That dual track made her a defendant in the Quinlan lawsuit alongside Giannoulias and Quigley, and her camp argued in that case that she had not been served, was not fundraising for mayor and had not declared, which is formally true and politically beside the point: she has also said publicly that she is running to stop Giannoulias. She brings assets no other late entrant could match, name recognition built over 28 years, a treasurer's office with a public reputation for publishing damning property tax studies, and a following that shows up at parades and community events across the county. Her reported cash on hand is modest for that profile, about $278,000 in recent rankings of the field, and she has no mayoral staff or formal campaign operation yet. If she files, she enters the top tier on recognition alone. Until she files, she is a pending candidacy, and this article treats her as one.
Below her, the field completes itself with four candidacies whose public records are brief enough to state in full. Jabari Taylor is a South Side native and health policy researcher at the University of Illinois Chicago, running on green social housing, an affordable public opt in insurance pilot and education to work pathways meant to keep younger Chicagoans in the city; his is a policy research record, with no elected office behind it. Jessica Maronto, who campaigns as Jesse Maronto, is a Chicago Department of Transportation traffic signal repair worker and IBEW member who lives in the Loop, running a No Poli-Tricks campaign that includes keeping 311 requests open until the work is actually fixed, weekly pay for lower paid city workers, teen safe spaces and food desert partnerships; hers is the only candidacy in the field from inside the city workforce that would be asked to run it. Johnny Logalbo is an addiction recovery counselor who has previously run as a write in candidate, building on recovery community networks. Mark Su is a businessman and a former candidate for the United States House from Illinois' 9th congressional district in 2026, which makes his the rare lower tier candidacy with a recent federal race behind it and no Chicago office or organization in front of it. For all four, the honest entry on signatures and money is the same: no filed signature total was reported on the first filing day, no cash on hand figure appeared in the third quarter summaries, and the filing window through October 26 will decide whether these are ballot candidacies or announcements. One more name belongs in the record precisely because it is no longer in the race: Liam Stanton, a Rogers Park small business owner who declared in February, withdrew on August 10 and endorsed Giannoulias, his committee still showing $91,869.79 in the third quarter roundup. His exit is the field's one worked example of the arithmetic that the rest of the lower tier is trying to beat.
Part Two: The Knockout File
Every campaign war room in Chicago is building the same document right now: not a biography of its own candidate, but a prosecution brief against everyone else. What follows is that brief, candidate by candidate, written the way an opponent would write it. Each entry names the weakest point, the single vulnerability most likely to end the candidacy, and then does the part campaigns skip in their own literature: it ties the attack to the record, to voting and office history, to lobbying and donor support, and to the coalition backing the candidate, so the reader can judge whether the attack is a slogan or an argument. These are attacks, framed as attacks. Where a charge rests on allegation rather than adjudicated fact, it says so.
Alexi Giannoulias: the promotion that hands his job to the governor
THE KNOCKOUT: He is asking Chicago to promote him out of a job Illinois just re-elected him to, and the fine print is that nobody gets to vote on his replacement. As laid out above, a Giannoulias victory in both races forces his resignation as Secretary of State before the May 17, 2027 mayoral oath, and the vacancy is filled by gubernatorial appointment, plausibly until a November 2028 special election. Opponents will compress that into one sentence that fits on a mailer: Alexi wants a new job so badly that he will let J.B. Pritzker pick the next Secretary of State, an unelected placeholder running one of the most patronage-heavy offices in Illinois, for over a year.
WHY IT STICKS: The Secretary of State's office is not an abstraction in Illinois. It is the office at the center of the state's defining patronage and corruption memory, the office George Ryan held on his way to the governorship and to federal prison, and the office whose driver-services and licensing functions touch every family in the state. Giannoulias ran for the office promising modernization and reform. An opponent's closing argument writes itself: the reformer's exit plan is an appointment. Layer onto that his earlier record, which opponents have never stopped citing: his tenure as state treasurer was shadowed by Broadway Bank, his family's bank, which federal regulators shut down in 2010, a collapse that followed the bank's loans to convicted figures and cost him his 2010 United States Senate race. That is adjudicated history, not allegation, and it gives the patronage attack a second verse about judgment and insiders. Finally, his coalition is his exposure: a $19.15 million war chest built substantially from the business, legal and real estate donor class and Springfield-adjacent labor support reads, in an opponent's ad, not as strength but as the machine reassembling itself with better branding. His defense, that vacancy law is the same for everyone and voters can weigh it openly, is legally sound and politically cold. It requires voters to think like lawyers. The attack only requires them to think like Chicagoans.
Brandon Johnson: the incumbent's record is the opponent
THE KNOCKOUT: He does not need to be beaten by a challenger. He needs only to be tied, daily, to his own four years. Johnson enters re-election with roughly $379,471 reported in the third quarter and a balance falling quarter over quarter, which opponents will present not as a fundraising footnote but as a verdict: the coalition that elected him in 2023 is no longer willing to pay for him.
WHY IT STICKS: Start with the budget. A $17.6 billion FY2027 proposal built around an $882.4 million gap, financed in part by a revived corporate head tax and a cloud lease tax, produced open revolt from aldermen and a business community that now funds his opponents. That is not an outside attack; it is his own council, on the record. Add the CTU question, the most durable structural attack on Johnson: he rose from the Chicago Teachers Union, the union was the financial and organizational engine of his 2023 campaign, and his administration then negotiated with that same union as the city's counterparty. Opponents do not need to allege corruption, and this article does not; the attack is structural conflict of interest, argued from his employment history, his donor and field support, and the contract fight itself. Add public safety symbolism that polls badly beyond his base, above all the decision to end the ShotSpotter contract, and the steady drumbeat of council-approved police misconduct settlements, including Guevara-era cases whose misconduct predates him but whose checks clear on his watch. Add the Springfield and Washington friction that defined stretches of his term, including the migrant-crisis fights with the governor's office. The composite attack is competence plus capture: a mayor captured by the union that elected him and unable to carry a budget, a council or a crisis. His counter, that he governed for working people against entrenched wealth, is a real argument. It is also the argument of a challenger, and he is no longer one.
Susana Mendoza: the Springfield insider running against Springfield
THE KNOCKOUT: She is one of the most experienced candidates in the field, and experience is exactly the problem. Two terms as Illinois comptroller and a term as Chicago city clerk make Mendoza a creature of the same state and city establishments this electorate keeps saying it wants to punish, and her years managing the state's bill backlog under and after the Rauner-era budget impasse tie her name to the worst fiscal years in modern Illinois history, however competently she managed within them.
WHY IT STICKS: Her support structure tells the story opponents will tell. Business donors, building trades and establishment Democratic networks are assets in a fundraising report and liabilities in a change election: every institutional endorsement confirms the frame that she is the continuity candidate. Her statewide voting-age record also gives opponents a geographic attack: she has already asked Illinois voters for promotion once, in the broader statewide arena, and Chicago's Southwest Side base, her strongest ground, overlaps almost exactly with the Latino wards Giannoulias and Cardenas are contesting, meaning her natural constituency is the most divided in the field. The closing attack is blunt: Chicago tried the experienced Springfield hand already, in other offices and other decades, and got the pension crisis and the backlog. Competence is her brand, and opponents will concede it, then ask what the competent management of a broken system is worth if she never once stood outside it.
Mike Quigley: Washington's candidate in a City Hall fight
THE KNOCKOUT: A long congressional career is a voting record, and a voting record is a target that never runs out of ammunition. Quigley has spent years voting on national questions in Washington, building a federal donor network and a North Side base, and opponents will ask the simplest question in the race: when Chicago was fighting over its budget, its transit funding and its migrant costs, its next mayor was casting votes in another city.
WHY IT STICKS: His coalition is narrow in the way congressional coalitions are narrow: strong on the North Side lakefront and in the establishment and federal donor world, unproven in the South and West Side wards that decide runoffs, and without the labor field operation or the ward organization that turns a respectable February showing into an April majority. Opponents will mine a decade-plus of House votes for the handful that play badly in a Democratic city primary electorate, on spending, policing and foreign policy, and present each as proof he answers to a national party rather than to fifty wards. His defense, federal experience and relationships that bring money home, is the same sentence every congressman-turned-mayoral-candidate has used, and Chicago voters have heard it before.
George Cardenas: an aldermanic base is not a citywide coalition
THE KNOCKOUT: Cardenas runs from the City Council, and the City Council is one of the least trusted institutions in Chicago. An aldermanic candidacy carries an aldermanic voting record: years of votes on budgets, zoning, tax increment financing districts and development deals in a single Southwest Side ward, each one available to opponents as evidence that his politics are transactional and ward-sized rather than citywide.
WHY IT STICKS: His support, rooted in his ward organization, business and development relationships and a pro-growth, public-safety lane, competes directly for Mendoza's and Giannoulias' voters without their money or their name recognition. In a field where the second runoff slot may be decided by a few points, the attack is not that he is wrong on an issue. It is that he is a spoiler with a council record, splitting the Southwest Side and the business lane while lacking the fundraising to survive a March runoff campaign. Chicago history is littered with credible aldermen who discovered in February that a ward is not a city.
Willie Wilson and the rest of the field: persistence without a path
THE KNOCKOUT: For Dr. Willie Wilson and the lower-tier and first-time candidates, the attack is arithmetic rather than scandal. Wilson has run for mayor and for the United States Senate before, retains a genuine church-based and South and West Side following and the ability to self-fund attention, and has never converted that following into a runoff. Opponents will treat his vote share, which in a fragmented field could still reach double digits, as the field's spoiler bloc: every point he holds is a point that keeps the second runoff slot within reach of a candidate much of the electorate ranks last.
WHY IT STICKS: The same logic, applied more harshly, covers the activist, independent and first-time candidates completing the field, among them candidates building from community, faith and small-business networks without major labor, donor or ward-organization backing. Their weakest point is the signature-and-money gauntlet itself: filing totals close to the 12,500 threshold leave them exposed to petition challenges, and fundraising an order of magnitude below the frontrunners leaves them unable to answer the first negative mailer. In Chicago, that is not a footnote. It is how candidacies end in December, before a single vote is cast, and opponents who cannot beat an argument can often afford to challenge a petition.
Matt Brewer: accused of the same closed door politics he is running against
THE KNOCKOUT: Brewer's candidacy was born in a process fight, and he has not won the argument about his own conduct in it. The mayor removed him as housing authority chair alleging that his board's move to hire a chief executive flew in the face of open meetings law and transparency rules. That is the mayor's allegation, not an adjudicated finding, and Brewer disputes the characterization. But an opponent does not need a finding. The attack writes itself: the candidate running against City Hall dysfunction was removed by City Hall for, on the mayor's telling, cutting a corner to install his own chief executive at the city's housing authority, and then asked voters to reward him with the mayor's office for it. Layered on top is the interest attack no other candidate carries in quite this form. Brewer co-owns a cannabis dispensary, Grasshopper Club, in an industry that the mayor of Chicago licenses, zones and polices, and co-owns a restaurant whose brand trades on insulting the incumbent. Every dispensary decision, every zoning fight, every enforcement call in a Brewer administration would be read through his ownership, fairly or not.
WHY IT STICKS: Brewer has no voting record and has never held elected office, which opponents usually call a gap. Here it is worse than a gap, because it makes the housing authority record the entire record. A decade on that board, the last stretch running it, means every failure of public housing in Chicago, every family on a waiting list, every building in poor condition, has his name on the governance chart, and the authority he led serves more than 63,000 families on a budget of about $1 billion. He cannot run as an outsider and cannot run as the authority's defender either, since his own launch video calls the status quo dysfunction. His resume, degrees from Stanford, Yale and Harvard and a partnership at Bartlit Beck, is elite in a way that helps with editorial boards and hurts in the wards his coalition math requires him to win, where opponents will cast the well credentialed lawyer with a hot dog stand and a dispensary as a man who has been on every side of the table except the tenant's. The surge case for Brewer is real. So is the sentence that ends it: Chicago tried electing the housing authority's man once already, in the sense that it has lived under his board for a decade, and the housing did not get fixed.
John Kelly: the casino's lobbyist asks to run the city
THE KNOCKOUT: No candidate in this field hands opponents a cleaner one line biography. For 28 years John Kelly was paid to influence City Hall on behalf of the interests City Hall regulates, including Bally's, the casino company, the White Sox and the United Center, and now he asks to sit on the other side of every one of those desks. De-registering for the campaign and promising to sell the business if he wins concedes the shape of the problem without answering it: the relationships, the clients and the debts of gratitude do not get sold with the firm. The casino tie is the sharpest version, because a Chicago mayor's decisions on gaming taxes, expansion and enforcement are worth real money to a former client, and Kelly's answer, that in 28 years there was never an ethical concern and that he is prepared to tell former clients no, is an assurance voters have heard from lobbyists before, usually from the other side of an indictment exhibit. While that argument was being made, a second one opened on its own: the Chicago Board of Ethics formally opened an investigation into campaign videos Kelly filmed inside city fire stations, a question about using city resources and city property as campaign scenery. Kelly has said the firehouse stops were a personal tour, with no literature distributed and no signatures collected. The investigation was a live matter in the reporting on his candidacy this fall, not a resolved one, and it is reported here as such.
WHY IT STICKS: Kelly's support structure is the attack's evidence. His $2.52 million, second in the field, comes substantially from the world he lobbied in, and every dollar of it lets an opponent say the special interests did not wait to buy the next mayor, they nominated their own salesman. His political support cuts the same way. Reporting has described national conservative and MAGA figures cheering his law and order candidacy, his campaign courting voters who backed Donald Trump in 2024, and his wife's prominent pro Trump online activism, in a city that votes overwhelmingly Democratic and where his own party identification has to be explained in interviews. A Sun-Times profile added a personal civil lawsuit by a construction contractor over the couple's Homer Glen home to the file opponents will circulate. None of this prevents Kelly from reaching a runoff in an eighteen-candidate declared field on money and conservative consolidation. All of it waits for him there, in a two candidate race in a liberal city, holding a lobbyist's client list with a casino on it.
Joe Holberg: a plan is not a record
THE KNOCKOUT: Holberg has been running longer than anyone in this field and the length of the run is the indictment. He announced in October 2025, published his platform as a book, raised more than $1.35 million, and when the first real poll of the race was published this fall he was, like every candidate except Giannoulias and the incumbent, below double digits. Opponents will not attack his biography, which is genuinely compelling, or his plan, which is more detailed than most. They will attack the category: he is a former math teacher who sold a financial wellness software company in 2023 asking to run a $17.6 billion city with a police department under a consent decree, having never held office, cast a vote, managed a public payroll or sat through a single budget hearing he was responsible for passing. His signature promises give the attack its arithmetic. One hundred thousand new homes and a balanced budget, delivered by a first time officeholder in one term, against an $882.4 million gap, invites the same spreadsheet question this article poses to the whole field, except that Holberg has no governing record to answer it with, only the plan itself.
WHY IT STICKS: His donor and support base, finance and technology professionals and reform minded homeowners, is exactly the constituency that defects first when a more credible vehicle for the same vote appears, and this field offers three of them in Quigley, Brewer and Giannoulias. The Crime Lab safety pledge he signed, alongside Mendoza, Quigley and Kelly, shows he can get into the right rooms. It also shows the company he is in: four rivals for the same competence vote, three of them with offices, staffs and records. A campaign that began earliest should, by the logic of organizing, own the outsider lane outright. Instead the outsider lane filled up behind him, which is the fact opponents will repeat until it sounds like a verdict: Chicago heard the fresh perspective pitch first from Joe Holberg, and kept shopping.
Lisa Nee: the diagnosis is not the management
THE KNOCKOUT: Nee's whistleblowing took courage and it is not in dispute. What opponents will dispute, relentlessly, is the inference her campaign asks voters to draw from it: that exposing unread heart tests at a federal veterans hospital qualifies a person to run the City of Chicago. The VA record is a record of refusal, of escalating a problem other people owned. A mayor owns the problems. There is no point in her documented career at which she has run a budget, managed a workforce at scale, negotiated with a union, or answered for a service failure that was hers, and her Kellogg MBA, which her campaign offers as the management credential, is a degree, not a tenure. Opponents will put it clinically, in her own profession's terms: she has diagnosed the patient in every interview. She has never been the surgeon, the hospital administrator or the person who has to tell the family what the operation costs.
WHY IT STICKS: The money makes the abstract attack concrete. Fifty thousand dollars on hand in the third quarter is not a citywide campaign, it is a speaking schedule, and in a field where the leader holds $19.15 million a candidate who cannot afford to answer the first attack mailer does not get to choose which argument defines her. Her support base, veterans advocates, healthcare networks and good government voters, is admirable and small, and it overlaps the Quigley and Holberg electorates, who can outspend her for the same voters by orders of magnitude. Her record is also, in the strict sense, in the wrong government: federal, clinical and a decade old in its signature episode, the 2015 Senate testimony. Chicago voters who want an honest outsider have fresher and better funded options, and the ones who want experience will not find a single day of it in city government on her file. Thin is the honest word for the record, and thin records do not survive February in Chicago. They survive, at best, as a profile that a future race can build on.
William Quinlan: the lawsuit was the campaign, and the lawsuit lost
THE KNOCKOUT: Quinlan built his entire candidacy on one legal theory, that his three best known rivals were illegally running for two offices at once, and the theory's first test in court ended on October 14 with a dismissal. Judge Reilly ruled the claim was not ripe and did not reach the merits, and Quinlan's response, that the ruling was about timing rather than substance and that he would appeal, may be good law and is unmistakable politics: the candidate whose pitch was that the rules disqualify everyone else could not get a judge to hear him. Opponents will also note who was missing from the caption. Cardenas holds a county office and a mayoral candidacy in exactly the posture the suit attacks, and he was not sued, a selectivity that lets rivals frame the case as strategy dressed as principle, aimed at the three names that frightened him. Then there is the money. His campaign's public claims of roughly $600,000 banked plus another $250,000 sat unresolved for weeks against state filings that listed $204,215, a gap trackers flagged openly. A candidate running on legal precision and clean process is the last candidate who can afford an unreconciled number in his own filings.
WHY IT STICKS: Strip the lawsuit away and there is no second act on file: no office held, no constituency organized, no signature total until a last day filing, no issue beyond the eligibility of other candidates. That structure makes his candidacy hostage to a docket. If the appeal fails or simply runs past November 3, the question his campaign exists to ask answers itself in the negative, in public, before a single mayoral vote is cast, and his own ballot line is left arguing that he was right too early. Even if the law eventually moved his way, the credit would belong to a court, not to a mayoral campaign, and voters choosing a mayor in a budget and crime crisis were never going to pay a finder's fee for a procedural point. The attack, in one sentence, is that Quinlan has spent his candidacy asking Chicago to disqualify the race instead of asking Chicago to vote in it.
Toni Brooks: a biography where a campaign needs to be
THE KNOCKOUT: This entry is labeled honestly at the top: Brooks' public record is thin, and the knockout against her is not a scandal hidden in it but the absence where a citywide record should be. She has never held elected office, cast a public vote or run a public agency, and as of this writing her campaign had produced no reported signature total on the first filing day and no cash on hand figure in the third quarter summaries, the two public tests every other serious candidacy in this article has passed or failed in the open. Her signature ideas invite the same scrutiny. A Citizen Responder volunteer network standing in for public safety capacity is a proposal opponents will describe as asking Chicagoans to volunteer for the job the city is supposed to hire for, and reallocating city funds, without a budget of her own on file, is a direction rather than a plan. Donating most of a first year salary is a gesture that costs a mayor nothing a budget would notice.
WHY IT STICKS: Her support is a community network, anti violence advocates, veterans, churches and neighborhood organizations on the South and West sides, and networks like that are strongest exactly where turnout operations are hardest to fund. In an eighteen-candidate declared field, sentiment does not circulate petitions, defend them against challenge or buy a single day of television, and the candidates competing for her voters, Johnson with the teachers union machine and Wilson with a decade of church based organization and self funding, both bring infrastructure she has not shown in a filing. Opponents do not need to say a word against her service, which is honorable. They only need to ask, at every forum, for the numbers: signatures, dollars, wards organized. Until her campaign answers in public documents rather than interviews, the kindest description of the candidacy is also the fatal one, a respected neighbor's run that the system is designed to process in December.
Danielle Carter-Walters: the lane that built her is the ceiling that holds her
THE KNOCKOUT: Carter-Walters is running as an open Republican, a co-founder of an organization called Chicago Flips Red, in a city where the Democratic nominee for president routinely takes four fifths of the vote and where the mayoralty has not been a realistic Republican project in living memory. The mayoral ballot is nonpartisan, but her identity is her brand, and opponents will not let a single undecided voter forget it: every Newsmax appearance, every joint event with Republican congressional candidates, every line about ending sanctuary city status will be mailed to Democratic households as proof that her campaign is a national conservative project with a Chicago address. That last promise also fails on mechanics, and opponents who do policy will say so. Chicago's sanctuary posture rests on the Welcoming City Ordinance and state law, neither of which a mayor repeals alone, so her signature pledge requires a City Council and a Springfield she does not have. Her other headline promises, forensic audits, indictments and prison time for the corrupt, describe the work of prosecutors and inspectors general, not of a mayor, and let rivals frame the platform as a prosecutor's campaign filed in the wrong race.
WHY IT STICKS: Her support base explains both her visibility and her limit. Chicago Flips Red's following, police families, conservative enclaves and a large national online audience give her attention out of proportion to her documented campaign: no third quarter cash figure in the published summaries, no reported signature total on the first filing day, no elected office and no voting record. An online audience is not a turnout operation, and February municipal elections in Chicago are won by ward level organization in bad weather. The deepest cut is the one her Democratic opponents and her Republican skeptics can make in the same words: that the candidacy functions, whatever its intentions, as a spoiler and a media platform, splitting the law and order vote that Kelly and Wilson are spending millions to consolidate while building a following that will still be there, monetizable and intact, the morning after she loses. In a race this crowded, being accused of running for the audience rather than the office is an accusation a candidate with no filings on the board cannot afford and cannot yet rebut.
Zoe Ma: the developer who would regulate developers
THE KNOCKOUT: Ma's candidacy carries its contradiction in its first line. She is a real estate developer and property manager running on affordability, property tax reform and a guaranteed income, asking voters squeezed by housing costs to trust a candidate whose livelihood is the housing market. Opponents do not need to allege anything improper, and nothing improper is alleged here. They need only repeat the biography: the landlord candidate, the developer candidate, a chair of the Cook County Green Party running as an independent in a city where the Green Party has no ward organization, no ballot line history in municipal races and no money. Her platform then supplies the arithmetic attack this article has aimed at the whole field. A guaranteed income program, expanded affordable housing and tax reform, promised simultaneously by a first time candidate with no budget document on file, against an $882.4 million structural gap, is a list of expenditures in search of a revenue source.
WHY IT STICKS: She is the newest candidate in the field, launched September 1, and it shows in the only places campaigns cannot fake. No cash on hand figure in the third quarter summaries, no signature total reported on the first filing day, no elected office, no voting record, no major endorsement reported: the public file on Zoe Ma is, as of this writing, a launch story and a website. Her potential base, Asian American voters, progressive independents, Bronzeville and South Side networks, is genuinely unclaimed by any other candidate, and opponents concede the symbolism of the first Chinese American candidacy for mayor. Symbolism, however, has a Chicago price, and it is 12,500 valid signatures defended against challenge, then a funded campaign in February. Candidates have built real movements from less. None of them did it starting in September with an empty public finance file, and the burden of being the exception is entirely hers to carry.
Maria Pappas: twenty eight years in office, still deciding
THE KNOCKOUT: Pappas is not yet a declared candidate, and that is the attack. She has held the Cook County Treasurer's office since 1998, told the public she plans to run for mayor and that she is running to stop Giannoulias, and still arranged to announce only after she has first been safely re-elected treasurer in November. Opponents will call the sequence what Quinlan's lawsuit already called it in court: a candidacy with a backup office, launched on a timetable that risks nothing. If she does file, the second attack is tenure itself. Twenty eight years administering one county office is the longest insider record in the field, longer than Mendoza's state service that Mendoza's own opponents call machine politics, and the treasurer's office, however well run, collects and invests money. It does not police a city, run its schools, its transit or its budget, and her celebrated property tax studies are reports about other officials' decisions.
WHY IT STICKS: Her support, decades of name recognition and a genuine popular following, is broad and shallow in the way courthouse fame is: voters know the pink shirt and the tax studies, and her operation, about $278,000 on hand and no mayoral campaign staff in place, is nowhere near the scale her recognition would need to convert before February. Every week spent waiting for November is a week the petition, fundraising and endorsement markets close without her, in a race where the filing window itself shuts on October 26, before her planned announcement window even opens, a timing problem her camp has yet to explain in public. If she stays out, the entry closes itself. If she comes in, she comes in as the candidate who wanted the office at the lowest possible personal risk, and Chicago's voters, who have buried safer candidates than her, will be invited to notice.
The rest of the lower tier: Taylor, Maronto, Logalbo and Su
THE KNOCKOUT, SHARED AND INDIVIDUAL: For Jabari Taylor, Jessica Maronto, Johnny Logalbo and Mark Su, the honest entry begins with the record, which is thin for each of them in a different way. Taylor, a health policy researcher, has a platform of genuine substance, green social housing and a public insurance pilot, and no experience of governing anything larger than a research agenda; opponents will call his candidacy a white paper with a filing fee. Maronto, a city traffic signal repair worker, runs from inside the workforce she would manage, which gives her a worker's credibility and an immediate conflict story for opponents, a mayor negotiating against her own union brothers and sisters, on top of a record with no budget or supervisory scale behind it. Logalbo, an addiction recovery counselor and a previous write in candidate, has the recovery community's trust and a prior campaign that did not reach the ballot as a printed name. Su, a businessman whose last race was a 2026 congressional candidacy in the 9th district, has no Chicago office, organization or documented city constituency at all.
WHY IT STICKS, FOR ALL FOUR: None of the four produced a reported signature total on the first filing day or a cash on hand figure in the third quarter summaries, and in Chicago those two absences are not paperwork, they are the campaign. The petition gauntlet that ends candidacies in December does not ask whether a platform is thoughtful, and the February electorate cannot vote for a name that December removed. Their realistic function in this race, unless a filing changes the picture by October 26, is the one the field's history assigns: forum voices who force an issue, housing, city workers, recovery, into rooms the frontrunners would rather keep on crime and budgets, and then a line in the record of a race decided by other people's organizations. That is a contribution. It is not a path to the fifth floor, and pretending otherwise in a document called the Knockout File would be the one dishonesty this section refuses.
The attack every candidate shares
One vulnerability covers the whole field, and the runoff will be decided by which campaign exploits it in the other finalist first. Chicago's next mayor must close a structural budget gap, manage a police department under federal consent-decree oversight, keep a transit system and a school system funded, and do it with a council that just demonstrated it will reject its own mayor's revenue plan. Not one candidate in this field has governed an organization of Chicago's scale through a fiscal contraction, including the incumbent, whose attempt is the record his opponents are running against. The knockout in this race, in the end, may not be a scandal, a bank, a union or an appointment. It may be a spreadsheet, presented in a debate in March, to a candidate who has run a brilliant campaign about everything except the arithmetic. Chicago has elected the better story before. It then spent four years living in the footnotes.
Reporting note: Fundraising figures reflect the most recent quarterly disclosures cited in the underlying research at the time of writing and will change with the next filing period. Petition totals are campaign-filed totals pending Board of Election Commissioners rulings on challenges. Prediction-market prices are snapshots of a thin market and are not polling. The Secretary of State succession timeline is a reading of Illinois vacancy law applied to a May 2027 resignation, identified in the text as analysis rather than settled precedent.
The Research Behind This Article
This article did not start as an article. It started as a piece of research, and readers who want to check its working, argue with its conclusions or simply explore the race at their own pace can go back to that source material directly.
The article is built on an interactive research brief we put together for this race: a deep-research report covering the full candidate field, the Secretary of State succession question, petition signatures, Kalshi prediction-market odds, campaign fundraising and the city budget, voter bases and voting patterns, and each candidate's ties to crime, lawsuits, cannabis, and casinos. Alongside the written report, the brief includes an interactive candidate explorer readers can click through, candidate by candidate, to compare the field on the measures the report tracks, from signatures and cash on hand to support bases and liabilities, rather than taking this article's narrative order or emphasis as the only way into the material.
The two pieces are designed to be read together. The brief is the evidence file: the full field, the numbers and the sourcing laid out in consultant-style sections that a reader can interrogate. This article is the story that evidence tells when a reporter is forced to choose what matters most, and the knockout file above is the part no campaign will write about itself. Where the article compresses, the brief expands. Where the brief hedges, with good reason, on a thin prediction market, an uncertified ballot or an unsettled question of vacancy law, the hedges are in the brief in full, and readers should hold this article to them.
