Incumbent Democrat Russ Feingold is still in a virtual dead heat with endorsed Republican challenger Ron Johnson in Wisconsin’s U.S. Senate race. The latest Rasmussen Reports telephone survey of Likely Voters in the state shows Feingold drawing 46% of the vote, while Johnson picks up 45%. Only three percent (3%) would vote for another candidate, and six percent (6%) are undecided.
Businessman Dave Westlake is challenging Johnson for the GOP nomination to be decided in a September 14 primary. Given that matchup, Feingold draws 47% of the vote to Westlake’s 41%. Four percent (4%) prefer another candidate, while seven percent (7%) are undecided. In match-ups with Westlake dating back to February, Feingold’s support has been stuck in a narrow 47% to 51% range. Westlake has earned between 35% and 38% support during that time.
Incumbents, like Feingold, who earn less than 50% of the vote at this stage of a campaign are considered potentially vulnerable. Feingold was reelected to a third term in 2004 with 56% of the vote. The survey of 500 Likely Voters in Wisconsin was conducted on June 21, 2010 by Rasmussen Reports. The margin of sampling error is +/- 4.5 percentage points with a 95% level of confidence.
