Beneath Cook County’s administrative building before sunrise Monday, the hallway filled with the scrape of handcarts and the thud of paper boxes as candidates hustled to the clerk’s counter. Among the early arrivals on Oct. 27 were County Board President Toni Preckwinkle and downtown Ald. Brendan Reilly, standing only a few feet apart. So were Assessor Fritz Kaegi and Lyons Township Assessor Pat Hynes, all angling for the same prize: a place on the March primary ballot—and, if luck and logistics break right, the coveted top line. The filing-day crowd reaffirmed a local ritual in which sheer presence doubles as a show of strength, according to Chicago Tribune.

  • Key dates: Filing opened Oct. 27 and runs through Nov. 3, per Chicago Tribune
  • Signature threshold: Democrats running countywide need at least 7,858 valid signatures; campaigns often gather multiples to survive challenges, according to Chicago Tribune
  • Preckwinkle’s haul: About 40,000 signatures and $282,000 raised last quarter; $622,000 cash on hand, per Chicago Tribune
  • Reilly’s cash edge: Personal loan of $100,001 helped fuel $913,000 raised last quarter; $1.4 million on hand at September’s end, according to Chicago Tribune
  • Assessor race: Kaegi reported 20,000 signatures and ended the quarter with $1.3 million; Hynes says he’ll maintain ethics reforms, per Chicago Tribune

A lobby of signatures

Being first on the ballot is widely believed to be worth a few extra votes, and candidates arrive before the 9 a.m. start to qualify for that chance drawing at the top slot—a test of organization that signals they didn’t need the extra days to scramble for support, according to Chicago Tribune. One candidate, Andre Smith, arrived at midnight to be first in line, as reported by Chicago Tribune.

Democratic hopefuls need at least 7,858 valid signatures to qualify, but campaigns typically push for triple the requirement to withstand challenges—and to project strength while carting in reams of petitions, according to Chicago Tribune. Preckwinkle unloaded what she estimated was about 40,000 signatures for herself and other countywide candidates endorsed by the party, her fifth time doing so, per Chicago Tribune.

Preckwinkle vs. Reilly: Record versus resources

Preckwinkle and Reilly are set for one of the county’s marquee contests. While her recent fundraising trailed Reilly’s, Preckwinkle leaned into her tenure. “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,” she said, according to Chicago Tribune. She added: “I have to confess that I didn’t collect signatures. I raised money.”

Reilly, who argues it’s time for a change, primed the race financially. He loaned his campaign $100,001 last month—using a well-known lever that lifts fundraising caps—and reported $913,000 raised in the most recent quarter, ending September with $1.4 million on hand, according to Chicago Tribune. The quarter included $50,000 checks each from Wheels Inc. founder Jim Frank, Howard Labkon, investor Matthew Pritzker and retired investor Thomas O’Reilly, per Chicago Tribune. Reilly said he gathered “around 21,000” signatures and spent recent weeks knocking doors and carrying petitions, pitching voters on “new eyes on old products.” “I think people are receptive to making changes in these big offices,” he said, according to Chicago Tribune.

Preckwinkle raised $282,000 last quarter and ended with $622,000 on hand, according to Chicago Tribune. Numbers aside, the signature margins hint at ground strength while the cash race foreshadows an air war.

Kaegi vs. Hynes: Ethics, endorsements and a familiar fight

The assessor’s contest is also drawing scrutiny. Kaegi is running without the Cook County Democratic Party’s endorsement this cycle, a dynamic that echoes his first outsider campaign. It’s “a lot of deja vu,” he said. Even without party backing, he estimated collecting over 20,000 signatures. “Voters want to see us fighting for them,” he said, adding he plans to push a bill in Springfield to allow more seniors to qualify for a local freeze on property tax assessments, according to Chicago Tribune.

Kaegi ended the quarter with $1.3 million in the bank, buoyed by a $500,000 loan earlier this year and contributions that included $100,000 from Fred Eychaner and $10,000 from Leo Smith, per Chicago Tribune. He suggested a vote for Hynes would mark a return to “obsolete cronyism,” pointing to Hynes’ donations from property tax and real estate interests, as reported by Chicago Tribune.

Hynes said those donations represent a small share of his total and dismissed Kaegi’s critique as “a red herring,” while stating he intends to keep in place the assessor’s broader ethics reforms, according to Chicago Tribune.

Crowded districts signal an energetic cycle

Beyond countywide races, filing opened for the County Board, Board of Review, judicial posts and township committeemen, according to Chicago Tribune. The North Side’s 12th District, being vacated by Commissioner Bridget Degnen, drew four early filers: Isaiah White, Cat Sharp, Jose “Che-Che” Turrubiartez Wilson and Liz Granato. Three filed in the 15th District since Commissioner Kevin Morrison stepped aside to run for Congress—Democrat Ted Mason and Republicans Daniel Lee and Gabriella Hoxie. In the 17th District, former Republican Commissioner Liz Doody Gorman filed to reclaim her old seat; Democrat Patricia Joan “Trish” Murphy also filed, along with Democrats Wesam Shahed and Sylvester Fulcher, per Chicago Tribune. Filing continues through Nov. 3, according to Chicago Tribune.

What the numbers say

Cook County’s size and political tilt shape every primary strategy. Home to more than 5.2 million people across a diverse electorate, the county is Illinois’ most populous and a Democratic stronghold, according to Wikipedia and Reference.org. In 2020, 74% of county voters backed Joe Biden, underscoring its blue identity, per Reference.org.

Even so, the political map features pockets of competitiveness: many areas are deep blue, but some neighborhoods split more evenly, data from BestNeighborhood shows. Education levels are high—about 40.82% of adults hold a bachelor’s degree or more—which often correlates with liberal voting patterns and informs the county’s Democratic lean, according to BestNeighborhood.

Rules of the road have changed

Recent Illinois primary reforms further elevate the stakes of this week’s paperwork. Legislative changes eliminated a pathway for local parties to install nominees without primary elections, an effort billed as boosting transparency, according to AP News. The shift drew opposition from critics who argue it restricts voter rights and ballot access, per AP News. In practice, the reforms push campaigns to over-prepare for the primary itself—collecting surplus signatures, filing early for ballot position, and building turnout operations months in advance.

Why it matters

Petition margins, fundraising, and ballot position are the opening moves in contests that will be decided by message discipline and ground organization. Preckwinkle is leaning on incumbency and a long record to contrast with Reilly’s fresh cash and change pitch, according to Chicago Tribune. Kaegi’s independent posture—without a party endorsement—puts his ethics and assessment reforms under a bright light, while Hynes’ vows to keep those reforms set up a direct credibility test, per Chicago Tribune.

Between now and March, expect the airwaves and doorsteps to feel the difference: Reilly’s financial head start promises an aggressive communications push; Preckwinkle’s signature show suggests a wide field network; Kaegi’s war chest and Hynes’ counterarguments will animate a race already primed by past debates, according to Chicago Tribune. In the districts, crowded fields like the 12th bear watching as local issues and organization meet a map that is overwhelmingly blue, yet not monolithic, data from BestNeighborhood shows. Filing week is only the prologue—but it’s a revealing one.
