Voter turnout for Michigan's midterm election was the highest in 56 years.
More than 4 million people cast ballots, with 4 percent of precincts still untallied as of Wednesday morning, according to unofficial results. That is at least 52 percent of the voting-age population — the most since 1962.
The high turnout led to a strong night for Democrats, who were on track to win all three statewide offices for the first time in 32 years and flipped two Republican-held congressional seats.
