Illinois voters pick a new generation of Democrats for House, Senate after near-record retirements

Illinois voters have elected a new generation of Democratic representatives to the House and Senate. This follows a period of near-record retirements within the state's Democratic party. The election took place in early 2026, with primary debates occurring in February. Numerous candidates vied for open congressional seats, including those in the 4th, 7th, and 9th districts. The election results signal a shift in Illinois's political landscape as younger Democrats replace outgoing officials.

On Tuesday, Illinois voters will participate in primary elections to nominate candidates for a U.S. Senate seat and five open congressional districts. The Democratic primary for Senate is a crowded race spurred by Senator Dick Durbin's retirement, featuring U.S. Representatives Raja Krishnamoorthi and Robin Kelly, and Lieutenant Governor Juliana Stratton. Krishnamoorthi has significantly outraised his opponents, while Stratton has gained momentum with support from Governor Pritzker. Due to Illinois' reliably Democratic lean, the primary winners are likely to win the general election and hold office for extended periods. State-level races, including Governor JB Pritzker's unopposed bid for a third term, are also on the ballot.
