All of Chicago’s 51 early voting sites — one in each of the 50 wards, plus the Chicago Board of Election Commissioners’ downtown office — will be open Monday Oct. 20 through Saturday Nov. 1.

Voters will be casting their ballots for governor, U.S. Senate, the General Assembly, the U.S. House and a number of other races. Voters registered in Chicago may use any early voting site — from 9 in the morning till 5 in the evening — in the city, regardless of where they live. You don’t need a reason to vote early.

Five regional sites — in the 4th, 19th, 28th and 47th wards, and the downtown elections office, 69 W. Washington St., Lower Level Conference Room — also will be open Sundays through Nov. 2.

Ballots cast in early voting are final; also, voters may not return to amend, change or undo a ballot for any reason. It is a felony to vote more than once — or to attempt to vote more than once — in the same election. An ID is not required, however, local elections officials advise each voter to have ID in the event there is a question about their registration.

All early voting sites will serve as “grace period registration” sites where voters may register for the first time or update the name or address on their existing registrations.
