Republicans have an 18-15 majority in the Senate.
MADISON, Wis. (AP) -- Democrat Ernie Wittwer is running for the state Senate in the southwestern Wisconsin district currently held by Republican Sen. Dale Schultz.
Wittmer announced his candidacy Tuesday in the Capitol outside the Senate chamber. Schultz is a moderate Republican who has not announced yet whether he will seek re-election.
Schultz has angered many in his party for a series of votes against Gov. Scott Walker's collective bargaining proposal, Walker's state budget this year and a bill making it easier to open a mine in northern Wisconsin.
Conservative Republican Rep. Howard Marklein is also running for Schultz's seat.
Schultz's campaign spokesman Todd Allbaugh says Schultz is considering running for the seat as an independent. Allbaugh says Schultz is still deciding whether to seek re-election.
MADISON, Wis. (AP) -- A Democrat plans to announce his candidacy for one of the most closely watched state Senate races in Wisconsin.
Ernie Wittwer, a longtime worker and budget director for the state Department of Transportation, planned to announce he was getting into the race Tuesday for the 17th Senate District.
That southwestern Wisconsin seat is held by moderate Republican Sen. Dale Schultz. He has angered many Republicans for his opposition to an iron ore mine in northern Wisconsin and his vote in 2011 against Gov. Scott Walker's collective bargaining changes.
Schultz has not said whether he will seek re-election. He did not immediately return a message left Tuesday.
Republican state Rep. Howard Marklein, of Spring Green, has already entered the race.
