LANSING, Mich. (AP) - Michigan election officials say 16 percent of the state's registered voters cast ballots in this week's presidential primary election.
The secretary of state's office said Thursday 1.2 million of the state's nearly 7.3 million registered voters participated.
About 21 percent of the state's registered voters took part in Michigan's 2008 presidential primary, when Republicans had a contested race but Hillary Rodham Clinton was the only major Democratic candidate on the ballot.
Luce County had the highest voter turnout on Tuesday with 27.5 percent of registered voters casting ballots. Baraga County was second with 27.25 percent. Ottawa County came in third with 25.5 percent voting.
Mitt Romney won the popular vote in his home state, but will split Michigan's 30 convention delegates with second-place finisher Rick Santorum.
