MADISON, Wis. (AP) _ Democratic state Sen. John Lehman says he is running for lieutenant governor, giving up the Senate seat he won in a 2012 recall election.

Lehman announced his lieutenant governor candidacy on Monday. He is the first Democrat to announce they are running for the post. Mary Burke is the only announced Democratic candidate for governor.

Lehman faced a tough re-election battle for the Senate seat that covers the city of Racine. Republicans redrew the district's boundaries in 2010, making it more favorable to Republicans.

Van Wanggaard, who defeated Lehman in 2010 but lost to him in the recall two years ago, has already announced he is running for the seat again.

Republicans currently hold an 18-15 majority in the Senate.
