2016

See also: United States Senate election in Wisconsin, 2016

The race for Wisconsin's U.S. Senate seat was one of nine competitive battleground races in 2016 that helped Republicans maintain control of the Senate. Incumbent Ron Johnson (R) defeated former Senator Russ Feingold (D) and Phil Anderson (L) in the general election on November 8, 2016.

In a rematch of the 2010 election, Johnson defeated Feingold for a second time to retain his Senate seat. Johnson trailed in the polls for most of the election. In the final weeks of the election, Johnson received funding from national Republicans. Johnson said, "I wish I would have had the cavalry show up in June, July, August when Feingold was using his little moneymaking machine to out resource me. I guess, better late than never."

Feingold reacted to his loss by saying to supporters, “I didn’t expect this outcome, to be honest with you.” Commenting on his loss and Democratic presidential nominee Hillary Clinton’s, Feingold said, “I would urge you to be as restrained as you can be as the next steps occur...this could be one the most challenging times in the history of our country.”

Johnson, who defeated Feingold by three percentage points, said in his victory speech, "I believe America has given us a chance, an opportunity to put this nation on the right path. It's exactly what I intend to do."
