Rasmussen survey shows Wisconsin very polarized in recall race - WKOW 27: Madison, WI Breaking News, Weather and Sports

MADISON (WKOW) -- In its latest survey of Wisconsin voters, Rasmussen Reports found 52 percent of them would not vote for Governor Scott Walker in a recall election.

But Scott Rasmussen was shocked by the polarizing views he found during the survey, in which 88 percent of voters said they have a strong opinion of Governor Walker. Specifically, 46 percent strongly disapprove of Walker and 42 percent strongly approve.

"The intensity of the opinion is unbelievable," Rasmussen told Business Insider in a phone interview Thursday. "We sometimes have people who are very unpopular and build up very strong negatives. We sometimes have governors who are very well liked. But to have basically nine out of 10 voters in the state have a strong opinion one way or the other for the governor is just amazing."

Four Democratic candidates are vying to challenge Walker in a June 5 election. 

Milwaukee Mayor Tom Barrett, former Dane County Executive Kathleen Falk, State Senator Kathleen Vinehout and Wisconsin Secretary of State Doug La Fallotte will face each other in a May 8 primary election.
