(CNN) - Former pro-wrestling executive Linda McMahon has closed the gap against Connecticut Attorney General Richard Blumenthal in the state's contentious Senate race, according to a new poll.
A Quinnipiac University survey released Tuesday indicates that McMahon, the GOP nominee, trails Blumenthal, the Democratic standard bearer, 49 to 46 percent among likely voters, with four percent undecided. Blumenthal's three point advantage is within the poll's sampling error, and is down from a six-point margin in a Quinnipiac survey from two weeks ago.
Nine percent who named a candidate say they may change their minds by the November election.
According to the poll, McMahon holds a five-point advantage among independent voters, a switch from two weeks ago when independents were split between the two candidates. The survey suggests a gender reversal, with McMahon leading among men by 12 points and Blumenthal leading among women by 17 points. The poll also indicates that those who say they are "angry" with the federal government back McMahon by a nearly four to one margin.
"With five weeks to go, the Connecticut Senate race is very close. Attorney General Richard Blumenthal is ahead by only a statistically insignificant three points. Blumenthal has to be concerned about Linda McMahon's momentum. He can hear her footsteps as she closes in on him," says Quinnipiac University Poll Director Douglas Schwartz.
"McMahon clearly is capitalizing on the anger that one-third of voters are feeling toward the federal government."
Nearly seven in ten voters approve of the job Blumenthal's doing as attorney general and 51 percent have a favorable opinion of him, with 41 percent saying they see him in a negative way.
According to the survey, McMahon has a 42 percent favorable rating, with 43 percent viewing her unfavorably.
"Usually debates don't make much of a difference, but in a race this close next month's debates could be a game changer," adds Schwartz.
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.
McMahon has spent over $20 million on her bid for the Senate. The poll suggests that a majority of Connecticut voters find her campaign commercials annoying, while only 42 percent say the same thing about Blumenthal's ads.
The poll's release comes just eight days after President Barack Obama teamed up with Blumenthal in Connecticut. The survey indicates that 45 percent of Connecticut voters approve of the job Obama's doing in the White House, while 51 percent disapprove.
The Quinnipiac University poll was conducted September 21-26, with 1,083 Connecticut likely voters surveyed by telephone with live interviewers. The poll has a margin of error of plus or minus three percentage points.
