Illinois primary election: Cook County Board President Toni Preckwinkle projected to win 5th term

Wednesday, March 18, 2026
COOK COUNTY, Ill. (WLS) -- Cook County Board President Toni Preckwinkle is projected to win her Democratic nomination and a fifth term, as no Republican candidate is running.

President Preckwinkle tells ABC7 this will be her final four years in office, and she hopes to go out in a meaningful way.

This is a breaking news update. The following is from an earlier report.

A pair of races on the Democratic side in Cook County have flooded the airwaves with campaign ads over the past few months, pitting incumbents against some fierce challenges.

One of them is the race for Cook County Board President.



The tough Democratic primary race for U.S. Senate maybe getting all the attention and money, but Cook County has two big races that center around issues that candidate Brendan Reilly say voters care about.

"You've seen lot of rhetoric about Donald Trump, while all Democrats running oppose his policies at the end of day it will likely decided on meat and potato issues," Reilly said.

Focusing on affordability and property taxes, downtown Chicago Alderman Brendan Reilly is challenging Toni Preckwinkle for Cook County Board President. Reilly says when she first ran for office in 2010, he was a strong supporter of hers. Preckwinkle, who turns 79 years old Tuesday, is seeking her fifth term.





"We're going to continue doing the good things that we've done with American rescue plan act resources, like eliminating medical debt, and we're going to do the best to defend ourselves against the assaults of the federal government," Preckwinkle said.

Preckwinkle is counting on voters to stay the course in her race for Cook County Board President.
