In an election for President of the United Stated in Wisconsin today, five days until votes are counted, Democrat Barack Obama defeats Republican John McCain 55% to 39%, according to this latest SurveyUSA poll conducted exclusively for WGBA-TV Green Bay, KSTP-TV Minneapolis and WDIO-TV Duluth. Compared to an identical SurveyUSA poll released two weeks ago, Obama is up 3 points; McCain is down 1. Among men, McCain has dropped to 40%, his lowest showing in 3 SurveyUSA tracking polls. If men drift back to McCain before election day, the contest in Wisconsin could be a couple points tighter than this data reflects. Obama has a significant running head start among those who tell SurveyUSA they have already voted. 800 adults interviewed 10/28/08 and 10/29/08. Of them, 741 are registered to vote; of the registered voters, 667 were determined by SurveyUSA to have already voted or to be likely to vote on or before November 4.
