Illinois: How to vote, where to vote and what’s on the ballot.

People in Illinois are voting on Tuesday in primary contests for the Senate, House and governor, among others. The outcomes will help set up the general election, which will help determine what party controls Congress for the next two years.

Not sure if you can vote? Can’t find your ballot? Have your ballot but don’t know where to send it?

Here is a handy, last-minute guide to help get you through Election Day.

How to vote

Not registered to vote? No worries. In Illinois, voter registration never closes, according to Matt Dietrich, a spokesman for the elections board. You can walk into a voting location and register to vote up until the time the polls close, he said.

The deadline to request a mail ballot was June 23. If you haven’t received it, you can sign an affidavit saying so at your polling place and be given an in-person ballot instead.

Mail ballots have to be postmarked no later than Election Day and be received within two weeks of Election Day.

Where to vote

On Election Day, voting sites open at 6 a.m. and close at 7 p.m. You can look up your polling location here.

What’s on the ballot

There are crowded statewide Republican primaries for Senate and governor, and nearly every congressional district has either a Democratic or Republican primary contest.

To see what is on your ballot, the elections board recommends contacting your local election authority; a list is available here. But this website may be a faster and simpler way to see the races that will be on your ballot.
