Illinois features an open U.S. Senate seat in 2026, on the ballot November 3, 2026, alongside the governorship and its congressional and state races. Here's a nonpartisan guide.
What's on the 2026 ballot in Illinois?
The U.S. Senate seat is open, with longtime Democratic incumbent Dick Durbin not seeking reelection, the first open race for this seat in decades and a magnet for a crowded field. The governorship is on the ballot, with Democratic incumbent J.B. Pritzker. Below them: all of Illinois's U.S. House seats, state offices, legislative races, and local contests.
What makes Illinois's races matter?
Illinois leans Democratic statewide, anchored by Chicago and its collar counties, so the open Senate seat is likely decided in a competitive Democratic primary, exactly the kind of small, engaged, high-information contest where a strong texting program matters most. The state's few competitive U.S. House districts, downstate and in the suburbs, add general-election battlegrounds.
Why turnout decides Illinois
An open Senate seat with a crowded primary puts a premium on mobilizing a small primary electorate, and a midterm lowers general-election turnout that decides the competitive House seats. Illinois's early and mail voting spreads the work across weeks.
