UNDATED (WTAQ) - Wisconsin's U.S. Senate race features a rematch of the last time this seat was up for grabs.
Back in 2010, Republican Ron Johnson knocked off then-incumbent Democrat Russ Feingold. Now it's Johnson's turn as the incumbent trying to stave off the challenge of Feingold.
Feingold has since taught at Marquette University in Milwaukee, Lawrence University in Appleton and Stanford University in Palo Alto, California. The Middleton native also served as United States Special Envoy for the Great Lakes Region of Africa and the Democratic Republic of Congo at the State Department.
The 61-year-old Johnson chairs the Homeland and Government Affairs Committee. Johnson also serves on the Budget, Foreign Relations, and Commerce, Science, and Transportation committees.
