What to expect

Polls close at 8 p.m. Eastern time. In the 2022 primaries, first votes were reported 5 minutes later, and 90 percent of votes were reported by 3:12 a.m. Eastern time. No excuse is required to vote by mail, and ballots must be postmarked by Election Day and arrive at least two weeks after.

Illinois is holding presidential primaries on Tuesday as well as its state primary, which will include races for state and congressional offices. Voters do not register by party, but they may participate in only one party’s primary election.
