MADISON, Wis., Nov. 8 (UPI) -- In Wisconsin, Sen. Ron Johnson, one of the most vulnerable Republican incumbents in the country, pulled off a huge upset, defeating former Sen. Russ Feingold in a race that could help the GOP retain control of the Senate.
Though once written off, polls showed the race tightening in the final two weeks, with much of Feingold's lead evaporating. The nonpartisan Cook Political report changed its rating of the race from "leans Democratic" to a pure toss-up a week ago.
