With Democratic Senator Herb Kohl of Wisconsin retiring, people are beginning to test the waters for running to replace him in 2012. Among them is GOP star Congressman Paul Ryan, who says he will decide
this week whether or not to run. Some people believe
that he will want to stay in the House of Representatives so that he can chair the powerful Ways and Means Committee. Potential challengers for the seat include former Congressman Mike Neumann, Senate Majority Leader Scott Fitzgerald, and Assembly Speaker Jeff Fitzgerald on the Republican side, and Congresswoman Tammy Baldwin, Congressman Ron Kind, and Milwaukee Mayor Tom Barrett on the Democratic side.
Update: He has decided
not to run, citing that he can have a bigger impact on policy in the House.
