Rahm Emanuel, Gery Chico, Carol Moseley Braun and Miguel del Valle are the leading candidates in Chicago's race for mayor.
Polls opened at 6 a.m. Tuesday across Illinois, but the race to watch is the one making political history in Chicago.
It's been 64 years since the city picked a mayor without an incumbent running, and on Tuesday, voters have their pick of six: Rahm Emanuel, Miguel del Valle, Carol Moseley Braun, Gery Chico, Patricia Van Pelt Watkins and William Walls, III, in the order they appear on the ballot.
If one candidate gets more than 50 percent, he or she will win the race outright. If not, the top two vote getters will face off in an April election.
Emanuel currently is polling beyond 50 percent as the clear front-runner, but political analysts say that with around 10 percent of Chicagoans still undecided, the race could see a runoff.
A record turnout is expected after more than 73,000 residents voted early, including Emanuel, del Valle and even retiring Mayor Richard Daley.
Election results also mark a new era of the city council, with a record number of 238 people running for alderman in 43 contested races.
Polls close at 7 p.m. Tuesday. If you have problems voting, call the Election Center, 312-269-7870.
