Ron Johnson

The outcome of next year’s battle between former senator Russ Feingold and incumbent Ron Johnson could determine which party controls the U.S. Senate.

The contest will be a rematch of 2010, when Johnson ousted Feingold.

Wisconsin first sent Feingold to the Senate in 1992. The Democrat was perhaps best known for shepherding through bipartisan campaign finance reform, and casting the lone “no” vote against the Patriot Act, after the 9-11 attacks.

Wisconsin Sen. Johnson is suing the administration for offering health care subsidies to Congress and its aides, if they buy plans on the federal exchange.
