From Chicago to across Illinois, voters headed to the polls on Tuesday to cast ballots in the state’s presidential primary election and other races.

Among the many races to be decided on March 19 include the Democratic Party nomination for Cook County State’s Attorney, pitting Clayton Harris III against Eileen O’Neil Burke, in a bid to replace Cook County State’s Attorney Kim Foxx, who announced in April 2023 that she would not seek reelection.

As of 10:30 p.m. Tuesday, the race was too close to call.

The “Bring Chicago Home” referendum, a real estate transfer tax hike proposed by Chicago Mayor Brandon Johnson, was also on the ballot. The question asks citizens to decide whether to impose higher real estate transfer taxes on homes and commercial properties that sell for more than one million dollars while reducing the rate for properties that sell for less than a million.

With more votes opposing the measure, “Bring Chicago Home” is likely to fail, though votes were still being counted Tuesday night.

As the ‘Bring Chicago Home’ referendum appears headed for defeat, the campaign says “our resolve to fight for housing justice continues.”

The Bring Chicago Home campaign exists in the long lineage of past and present struggles for fair housing, civil rights, and economic justice. While tonight’s election results are disappointing, we are nowhere near the end of our journey. 

There are still 100,000 outstanding mail-in ballots to be counted, but whatever the final count, one thing is abundantly clear tonight: how determined our opponents are to continue profiting from displacement and inequality. From landlords sending intimidating emails to tenants to a legal challenge attempting to invalidate the results, the realtors, corporate landlords, and mega-developers fought us at every turn.

Our broad-based coalition–made up of homeless and formerly homeless people, union members, faith leaders, social service providers, community organizations, and grassroots volunteers–is determined to keep fighting for housing justice. Together, our city-wide field program knocked over 300,000 doors, made over 600,000 phone calls, and sent over 1 million text messages across all 50 wards. This is the work that makes our movement stronger over the long haul, no matter the final result.”
