Republican Linda McMahon is closing in on Democratic state Attorney General Richard Blumenthal in the Connecticut Senate race, according to a new poll by Quinnipiac University.
Blumenthal, once thought to be a lock for the seat, currently leads McMahon by 49 percent to 46 percent, according to the poll. Quinnipiac's margin of sampling error is three points, and four percent of respondents said they were undecided.
CBS News rates the race as having a "Democratic Edge."
McMahon, the former CEO of World Wrestling Entertainment, has climbed three points since two weeks ago, when a Quinnipiac poll put Blumenthal ahead by six points, with a 51 percent to 45 percent lead.
Blumenthal entered the race as a clear favorite in January, but has slipped significantly in polls since May, when the New York Times reported that he had been inaccurately describing his service in the Vietnam War.
Blumenthal and McMahon are vying for the seat of longtime Democratic Sen. Chris Dodd, who announced his retirement in January amid signs of a potentially tough bid for re-election.Critical Contests: Interactive Map with CBS News' Election 2010 Race Ratings
