Detroit's elections director says he expects a turnout of 10 percent 12 percent in Tuesday's presidential primary, with the only contest on the Republican side and the city leaning heavily Democratic.

Daniel A. Baxter said Thursday that he's received 20,500 absentee ballots out of about 30,000 applications sent out. He says only 2,004 were sent to people registered as Republicans.

The Republican primary is hotly contested, but people voting Democratic have a choice between President Barack Obama and uncommitted delegates. The Democratic Party isn't picking its delegates until caucuses on May 5.

Detroit has 529 polling precincts for its 550,874 registered voters.

There are no other issues on the ballot, and Baxter says many voters will cast ballots out of pride in not missing an election.
