Immediately after the polls closed at 7:00 pm Central Time, the Associated Press declared former vice president Joe Biden the winner of the Illinois primary. Biden was victorious in all but one county, Champaign County, winning 59% of the vote and 95 delegates, while senator Bernie Sanders received the rest of 36% and 60 delegates. Together with his victories on the same day in Florida and Arizona, Biden greatly expanded the gap in delegates between him and Sanders. Voter turnout was significantly down from 2016, due to the closure of polling places as a result of the COVID-19 pandemic.
