Connecticut Senate Race: McMahon Up by 3

Two recent polls, including a new survey released Tuesday from Quinnipiac, show Republican Senate candidate Linda McMahon of Connecticut slightly leading her Democratic opponent, congressman Chris Murphy. The Quinnipiac poll shows McMahon 3 points ahead of Murphy, 49 percent to 46 percent, while a Rasmussen poll released last week shows McMahon ahead by the same margin, 49 percent to 46 percent.

The seat, currently held by retiring independent Democrat Joe Lieberman, is considered a toss-up. The RealClearPolitics average of polls shows Murphy with less than a one-point lead. Barack Obama is expected to win Connecticut, which he won by more than 20 points in 2008.
