Poll Results for Kohl's Senate Seat.

A new poll shows ex-Gov. Tommy Thompson has the highest name recognition and the most favorable ratings in Wisconsin's U.S. Senate race.

But the Marquette University Law School poll released on Wednesday shows the public is largely unfamiliar with the candidates who want to replace retiring Democratic Sen. Herb Kohl.

The poll shows 49 percent think favorably of Thompson compared to 31 percent who don't. Other Republicans include former U.S. Rep. Mark Neumann, who has a 27 percent favorable rating and 18 percent unfavorable.

Fifteen percent view Assembly Speaker Jeff Fitzgerald favorably, while 18 percent were unfavorable. Democratic Congresswoman Tammy Baldwin had a 23 percent favorable rating compared to 21 percent unfavorable.
