CHICAGO — Are you ready for the runoff?
For the first time since Chicago introduced the runoff, the mayoral race features a head-to-head battle after Rahm Emanuel in February failed to get more than 50 percent of the vote, a requirement for re-election.
Voters across the city's 50 wards will have a chance to vote for the mayor or his challenger, Jesus "Chuy" Garcia, when they go to the polls Tuesday.
Meanwhile, residents in 18 of the city's 50 wards will choose who they want for alderman. To find your polling place click here.
Here's a guide to those 18 races:
A few things to keep in mind:
• If you voted in the February election, your ballot does not carry over to the runoff election. You must cast a ballot again for it to count in the runoff.
• If you didn't vote in the February election, you can still vote in the runoff election.
• Unlike the February election, there will be no write-in ballots allowed. There are only two candidates for each office up for grabs. The person with the most votes wins the job.
