Voting has already started in a scattering of locations.

Here’s when early voting begins in a few states.

Illinois — Sept. 29 to Nov. 7. Starting Sept. 29, voters can only cast their ballots at their local election authority or a temporary location, but early voting expands to permanent polling places starting Oct. 24.

Indiana — Oct. 12. Early voting starts at the local county election board office or another designated location, but with an excuse, voters can cast a ballot by mail.

Michigan — There is no early voting in Michigan, as voters require a state-approved excuse to vote absentee.

Minnesota — Sept. 23

Ohio — Oct. 12.

Wisconsin — Early voting opening dates are set by the county/municipality. Wisconsin Rapids began voting Sept. 19.
