(CNN) – With one day to go until the midterm elections, a new poll indicates that Richard Blumenthal has a nine point lead over Linda McMahon in the Senate battle in Connecticut.
According to a Quinnipiac University survey released Monday morning, 53 percent of likely voters in Connecticut say they back Blumenthal, the longtime state attorney general and Democratic nominee for Senate, with 44 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. Three percent of voters are undecided.
Blumenthal's nine point lead is down 3 points from an 12-point advantage in a Quinnipiac poll conducted last week. A Suffolk University survey released two weeks ago indicated Blumenthal with an 18 point lead but other recent polls suggest he held 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 93 to 6 percent among Democrats ,while McMahon leads 87 to 13 percent among Republicans. The poll indicates McMahon has a 49 to 44 percent advantage among independent voters. Last week, Blumenthal had a 16 point advantage among independents. According to the survey, women back Blumenthal 61 to 36 percent, with men supporting McMahon 50 to 46 percent.
"Linda McMahon's mini surge may be too little, too late," says Quinnipiac University Poll Director Douglas Schwartz. "Independent voters, who have been very volatile in this election season, are shifting back to the Republican candidates in both the Senate and governor's races."
In the gubernatorial contest, the poll indicates that 48 percent of likely voters support Republican Tom Foley, with 45 percent backing Democrat Dan Malloy. Foley's three point advantage is within the survey's sampling error, indicating the race is neck and neck. Last wek Malloy held a five point advantage over Foley.
Malloy is mayor of Stanford. Foley is a former ambassador. The winner in November will succeed Republican Gov. Jodi Rell, who announced last year that she would not run for re-election.
The Quinnipiac University poll was conducted October 25-31, with 930 likely voters in Connecticut questioned by telephone. The survey's sampling error is plus or minus 3.2 percentage points.
