Your guide to voting in Chicago's runoff elections

Zoom in: In Chicago, polls suggest we're in for a super-tight mayoral race, meaning turnout today could play a huge role and every vote will count.

What they're saying: "If it's a close mayoral race on election night, it may take one to two weeks to see how the majority of the outstanding vote-by-mail ballots shake out," Chicago Board of Elections spokesperson Max Bever tells Axios, noting they have until April 18 to issue an official determination.

Be smart: If you still haven't made up your mind, or even glanced at who's running, we've got you covered with guides to:

• Alder runoffs
• Suburban races
• Plus, a look at political and celebrity endorsements, and who would sway you.

Where: Look up your Chicago and other Illinois poll locations here.

When: Polls open at 6am and close at 7pm.

• If you're voting by mail, your ballot must be postmarked by today.

Who: All Chicago residents 18 and older can vote, and same-day provisional registration and voting are allowed with proper ID.

🔮 Our prediction: The winner of Chicago's mayoral race will be a guy … with glasses … and a goatee.

• That's just a strong hunch.
