Marquette Poll: Thompson 46, Baldwin 45
Updated at 3:00 p.m.
The Wisconsin Senate race is a dead heat, according to a new Marquette University Law School poll released Wednesday.
The survey shows former Wisconsin Gov. Tommy Thompson with a 46 percent to 45 percent advantage over Democratic Rep. Tammy Baldwin. Six percent of likely voters remain undecided. Thompson's razor-thin edge is well within the survey's margin of error. In the previous poll, conducted in late September, Baldwin led Thompson, 48 percent to 44 percent.
After narrowly escaping the GOP primary in August, Thompson, who has won four gubernatorial elections in the state, began the general election campaign as the favorite. But Thompson ran out of money at the end of the competitive GOP primary, causing his campaign to go dark on television for several weeks. Several polls released in September showed Baldwin with a narrow lead, but the race has tightened with both sides now spending heavily on television.
The poll also shows a tight presidential race in Wisconsin, with President Obama ahead of Mitt Romney, 49 percent to 48 percent. Obama had a significant lead -- 53 percent to 42 percent -- in late September. The poll was conducted after the first presidential debate in Colorado but before Tuesday's debate in New York.
Baldwin and Thompson both suffer from poor favorability ratings. Thirty-seven percent of likely voters view Thompson favorably, while 50 percent view him unfavorably. Similarly, thirty-two percent of respondents have a favorable opinion of Baldwin, while 47 percent have an unfavorable view of the congresswoman.
