CHICAGO — After months of campaigning, debates and oh-so-many mailers, it’s finally Election Day in Chicago.

The polls opened at 6 a.m. across the city and will close at 7 p.m.

Tuesday’s runoff will decide the winners of races that weren’t already decided in the Feb. 28 election. All Chicagoans will vote on the city’s next mayor. And while some aldermanic seats have already been won, residents in 14 wards will be voting on their next alderperson.

And remember: If you’re in line to vote by 7 p.m., stay in line.

Here’s everything you need to know about voting Tuesday.

And here are the races we’re watching:

The Race For Mayor

Former CPS CEO Paul Vallas and Cook County Commissioner Brandon Johnson will face off to become the next mayor.

So far, the neck-and-neck race has seen 184,723 early ballots cast, outpacing the previous two mayoral elections, said Max Bever, Chicago Board of Election Commissioners spokesperson. There were also 107,868 vote by mail ballots returned to the board as of Monday and 91,838 outstanding ballots.

Though all returned ballots will be counted Tuesday when polls close, the number of outstanding vote-by-mail ballots could mean there is no clear winner Tuesday night, Bever said.

Unsure who to vote for?

14 Wards To Watch

While most Chicagoans will just be voting for mayor, 14 ward races are also up for grabs.

A Block Club analysis found more than $21 million has poured into City Council races, including $18 million in direct donations to candidates’ campaign funds and $3 million more spent independently by outside groups. The money has paid for a series of proxy wars, pitting longtime City Hall insiders or pro-business candidates against independents and progressives.
