Democrat Richard Blumenthal has reasserted his lead over Republican Linda McMahon in Connecticut's Senate race, according to a new poll out Thursday.

The numbers have seesawed back and forth during the past few weeks, but the former World Wrestling Entertainment CEO now finds herself trailing by an 11-point margin.

New numbers from Quinnipiac University show Blumenthal with the lead — 54 percent to 43 percent. Another 3 percent of likely voters remain undecided, while 7 percent said they intend to vote for someone else.  

The numbers show sizable movement from a Q-poll late last month, which had Blumenthal ahead by just 3 points — 49 percent to 46 percent.

"Fueled by a surge in support from women, Democrats and independents, Attorney General Richard Blumenthal has his best poll numbers since the start of the fall campaign,” said Quinnipiac University Polling Director Douglas Schwartz.

The McMahon campaign dismissed the new numbers Thursday, saying the movement toward Blumenthal is likely thanks to recent attack ads hitting McMahon, which the campaign labeled "misleading and untruthful." 

"We have always said this election will be close, and as is typically the case in close elections, polling will fluctuate," McMahon spokesman Ed Patru said in a statement. 

The poll found women supporting Blumenthal 66 percent to 32 percent, while Democrats back him by a commanding 95 percent to 4 percent margin and independents back him by a 49 percent to 44 percent margin. 

The independent vote has flip-flopped since the Sept. 28 poll, when it favored McMahon 49-44 percent.  

As state attorney general, 57 percent to 38 percent of likely voters have a favorable opinion of Blumenthal and 69 percent to 26 approve of the job he is doing. McMahon’s favorability is split at 46-46.  

First lady Michelle Obama, who has spent time campaigning for Blumenthal, received a 56 percent to 28 percent favorability rating. But 76 percent of likely Connecticut voters say her campaigning won’t impact their decision in November. 

President Obama wins approval from 47 percent of likely voters. 

The poll surveyed 1,119 likely Connecticut voters and has a margin of error of plus-or-minus 2.9 percentage points.
