(CNN) - A new poll indicates that Richard Blumenthal maintains a double digit lead over Linda McMahon in the Senate battle in Connecticut.
According to a Quinnipiac University survey released Tuesday, 54 percent of likely voters in Connecticut say they back Blumenthal, the longtime state attorney general and Democratic nominee for Senate, with 42 percent supporting McMahon, the GOP nominee and former pro-wrestling executive who's spent tens of millions of dollars of her own money on her campaign.
Blumenthal's 12 point lead is up one point from an 11-point advantage in a Quinnipiac poll conducted earlier this month. A Suffolk University survey released last week indicated Blumenthal with an 18 point lead but other recent polls suggest he holds only a single digit advantage over McMahon.
The winner in November will succeed five-term Democratic Sen. Chris Dodd, who announced earlier this year that he would not run for re-election. A GOP Senate victory in Connecticut would give the party a big boost towards possibly reclaiming control of the chamber.
According to the new Quinnipiac poll, Blumenthal leads 86 to 12 percent among Democrats and 56 to 40 percent among independent voters, while McMahon leads 85 to 10 percent among Republicans.
The survey indicates that 55 percent of likely voters have a favorable opinion of Blumenthal, with 39 percent seeing him in a negative light. Forty-three percent of likely voters have a favorable opinion of McMahon, with 51 percent seeing her in a favorable light.
"Linda McMahon has tried to raise Attorney General Richard Blumenthal's negatives over the last several weeks, but she hasn't been successful. He remains popular, but McMahon's own negatives have risen above 50 percent," says Quinnipiac University Poll Director Douglas Schwartz. "One has to wonder if over the last few weeks McMahon would have been better off spending more of her millions on positive ads.
The Quinnipiac University poll was conducted October 18-24, with 702 likely voters in Connecticut questioned by telephone. The survey's sampling error is plus or minus 3.7 percentage points.
