Online voter registration through state website closes Sunday ahead of Nov. 3 election
Early voting sites outside election offices must open weekends starting Monday, state calendar says
CHAMPAIGN - Sunday, Oct. 18, is the last day Illinois voters can register through the State Board of Elections' website for the Nov. 3 general election, according to the board's election calendar.
Starting Monday, Oct. 19, early voting begins at permanent polling places other than the election authority's own office, the calendar shows. State law requires those polling places to be open on holidays, Saturdays and Sundays.
Oct. 19 is also the last day a vacancy in a party's nomination can occur and be filled for the general election, the calendar says.
The same day, filing opens for some municipal candidates in the consolidated primary, including established-party candidates in municipalities with more than 5,000 people. The state board notes that this filing period does not cover candidates for park, library, school, community college or fire protection district offices.
The state calendar does not list local early voting sites or hours. In Champaign County, those are posted by the County Clerk's office.
