Democrat Rob Zerban says he will jump into another race to try to unseat GOP Congressman Paul Ryan. Ryan turned back Zerban 55 to 43 percent in 2012.
Zerban says he will launch his 2014 campaign this weekend in Kenosha. He has served a couple terms on its county board.
While Ryan defeated Zerban last year by 12 percentage points, the margin was the incumbent's smallest margin of victory since first winning a seat in Congress in 1998.
