Wisconsin voters chose Donald Trump in 2016 but Joe Biden four years later, and it was close both times, so Wisconsin could go either way in this election, with a nearly evenly divided electorate, splitting most public opinion polls.

In a close race, both sides are trying to gain ground with new voters.

For Republicans that means trying to cut into Democrats' historic advantage with black voters.

Four years ago, Biden won Wisconsin by fewer than 21,000 votes but carried Milwaukee by more than 145,000 votes.

Analysis by Marquette University says 53% of those winning ballots for Biden came from majority-black wards.

Trump told supporters that his multiple criminal indictments have helped him with black voters.
