The filing day scene

Dragging carts stacked with paper, candidates for Cook County offices packed the hallway beneath the county’s administrative building before dawn Monday to secure their spots on the March primary ballot. By the 9 a.m. official start of filing on Oct. 27, the line had become a familiar pre-election tableau — part ritual, part show of strength — featuring some of the county’s most-watched contenders standing just feet apart, according to Chicago Tribune.

Incumbent County Board President Toni Preckwinkle and downtown Ald. Brendan Reilly arrived early, reflecting the stakes of a race expected to draw money and attention. Nearby, Cook County Assessor Fritz Kaegi submitted his petitions as he seeks a third term, with Lyons Township Assessor Pat Hynes mounting a challenge. The first-day crowd also included hopefuls for County Board seats, the property tax Board of Review and judicial posts, as filing opened countywide and continues through Nov. 3, Chicago Tribune reported.

Being among the first to file can yield an advantage: the top name on the ballot is widely viewed as worth a few extra votes. Arriving early also signals organizational muscle — proof a campaign didn’t need the weekend to scrounge for more signatures and is ready for the fight ahead, a dynamic emphasized by the filing-day choreography documented by Chicago Tribune.

The big races and the money behind them

Preckwinkle unloaded what she estimated was about 40,000 signatures — a towering stack that also covered other countywide candidates endorsed by the Cook County Democratic Party. “I think we have a great record over the last 15 years of good fiscal management, of creating a health care system where we can deliver quality health care and, as I said, insure 400,000 people in Cook County, and we work together with the city and state to make our criminal justice system more fair,” Preckwinkle said, before adding, “I have to confess that I didn’t collect signatures. I raised money,” according to Chicago Tribune.

Reilly, the 42nd Ward alderman, said it’s time for “new eyes on old products.” He told the Chicago Tribune he gathered “around 21,000” signatures and carried petitions with him in recent weeks, saying, “I think people are receptive to making changes in these big offices.” On the money front, Reilly loaned his campaign $100,001 last month — a strategic number that lifts contribution caps — and quickly collected four $50,000 checks, from Wheels Inc. founder Jim Frank, Howard Labkon of the General Iron family, investor Matthew Pritzker and retired investor Thomas O’Reilly. He raised a total of $913,000 in the most recent quarter, including $120,000 from a separate 42nd Ward fund, ending September with $1.4 million on hand, according to Chicago Tribune.

Preckwinkle raised $282,000 that same quarter and reported $622,000 in cash on hand, Chicago Tribune reported.

In the assessor’s race, Kaegi finished the quarter with about $1.3 million in the bank, cushioned by a $500,000 loan earlier this year, and received $100,000 from media mogul Fred Eychaner and $10,000 from Leo Smith last quarter, according to Chicago Tribune. Running without the county Democratic Party’s endorsement, Kaegi called this cycle “a lot of deja vu,” likening it to his first outsider campaign. He estimated his team collected more than 20,000 signatures and said voters “want to see us fighting for them,” while signaling he’ll push in Springfield for a bill to let more seniors qualify for a local freeze on property tax assessments. He also suggested a vote for Hynes would mean a return to “obsolete cronyism,” noting Hynes has taken contributions from property tax and real estate interests. Hynes countered that such donations make up a small portion of his fundraising, calling Kaegi’s suggestion “a red herring” and pledging to keep the ethics reforms Kaegi instituted, according to Chicago Tribune.

Why signatures matter

Democrats running countywide must submit at least 7,858 valid signatures to qualify for the ballot, but campaigns typically aim to collect roughly three times that figure to guard against challenges and project strength, according to Chicago Tribune. Analysts note that big petition stacks and first-day filings serve as organizational signaling — evidence of volunteer networks, field capacity and administrative chops that can shape media narratives and donor confidence, insights reflected in recent county contests and reporting from WBEZ and the Chicago Tribune.

The 9 a.m. cutoff to be in the lottery for the top line adds to the urgency. As campaigns roll out their paper tallies, they telegraph momentum as much as math — and with a tradition of aggressive petition challenges in Illinois, surplus signatures can be a candidate’s best insurance policy, according to WBEZ.

The numbers at a glance

  • Signature minimum for countywide Democrats: 7,858; typical target: roughly 3x the minimum, per Chicago Tribune.
  • Preckwinkle signatures: about 40,000; Reilly signatures: “around 21,000,” according to Chicago Tribune.
  • Reilly financing: $100,001 loan; $913,000 raised last quarter; $1.4 million cash on hand, per Chicago Tribune.
  • Preckwinkle financing: $282,000 raised last quarter; $622,000 cash on hand, according to Chicago Tribune.
  • Kaegi financing: about $1.3 million cash; notable donors include Fred Eychaner ($100,000), per Chicago Tribune.

Crowded fields down-ballot

The first day brought a flurry of County Board filings. The 12th District on the city’s North Side, vacated by Commissioner Bridget Degnen, drew four Democratic hopefuls by Monday morning — Isaiah White, Cat Sharp, Jose “Che-Che” Turrubiartez Wilson and Liz Granato — making it the day’s most crowded contest at the county level, according to Chicago Tribune.

In the 15th District, where Commissioner Kevin Morrison is running for Congress, Morrison’s chief of staff Ted Mason filed as a Democrat, and Republicans Daniel Lee and Gabriella Hoxie also filed. In the 17th District, former Republican Commissioner Liz Doody Gorman filed to run for her old seat. Patricia Joan “Trish” Murphy, daughter of the late Democratic Commissioner Joan Patricia Murphy, filed as well, and Democrats Wesam Shahed and Sylvester Fulcher also entered the race, filings that underscore the cross-party competition in the northwest and southwest reaches of the county, according to Chicago Tribune.

The political reality in Cook County

Cook County is the nation’s second-most populous county and a Democratic stronghold that includes Chicago and a vast, diverse suburban belt. As of 2020, the county had 5,275,541 residents and in 2020 gave 74% of its vote to Joe Biden, according to Wikipedia. Democrats expanded their dominance on the County Board in 2022, winning 16 of 17 seats, while the party also held the State’s Attorney’s office in 2024 as Eileen O’Neill Burke won the race to replace Kim Foxx, outcomes that help frame expectations for 2025–26 contests, according to Wikipedia and WTTW.

Money is likely to loom large. Recent countywide races have shown how concentrated donations can accelerate name recognition and voter contact, particularly in a county where turnout varies starkly by neighborhood, analysts noted in coverage by WBEZ and Axios. That puts a premium on early fundraising hauls like Reilly’s — and on how efficiently campaigns convert dollars into field operations and paid messaging.

What comes next

With filing open through Nov. 3, petition challenges, ballot order lotteries and finance reports will shape the contours of the March primary. The top-of-ticket battles — Preckwinkle-Reilly for Board president and Kaegi-Hynes for assessor — are already defined by contrasting strategies: paper power and incumbency on one side, outsider critique and fundraising muscle on the other, according to Chicago Tribune.

In a county that reliably votes blue but contains stark turnout disparities and divergent neighborhood priorities, the campaigns that pair strong petition operations with well-funded, targeted outreach could have the edge, analysts suggest, drawing on patterns observed by WBEZ and Axios. The filing-day theater has ended; the organizing — and persuading — starts now.
