The number we're talking about is the percentage of the population old enough to vote.
Less than half of those people showed up at the polls on Election Day in Michigan.
Voter turnout for this year's election came in at 41.6%. In Michigan's last gubernatorial election four years ago, 42.9% of the voting age population turned up to vote.
Michigan's secretary of state's office reports that about 3.2 million votes were cast Tuesday - around 83,000 fewer than in the 2010 midterm election.
To find a lower turnout stat for midterm or presidential elections, you have to go back to 1990 in Michigan.
Here's a chart showing the history of voter turnout in Michigan since 1948. It shows gubernatorial election years and presidential election years. Presidential elections traditionally draw more people to the polls - hence the zig-zag. (The Pew Research Center has more on why that is.)
