HARTFORD, Conn. In a race that is gaining more attention nationally, Republican Linda McMahon and Democrat Chris Murphy are locked in a statistical dead heat for the U.S. Senate seat in Connecticut.
The latest poll by the University of Connecticut and the Hartford Courant, which is owned by Tribune Co., shows Murphy with 37 percent to McMahon's 33 percent, within the margin of error of plus or minus 4.4 percentage points.
The survey also found that 28 percent of likely voters say they are undecided.
As the candidates batter each other with a barrage of negative TV commercials, the race remains a tossup with less than seven weeks to go before the election.
Connecticut voters have selected Democratic candidates in every presidential race since 1992. In the 2008 presidential race, Democrat Barack Obama defeated Republican John McCain by more than 20 percentage points in Connecticut.
Republicans have not won a U.S. Senate race in Connecticut since 1982, when Lowell Weicker Jr. won the seat.
Joe Lieberman, a Democrat-turned-independent, is retiring after 24 years in the Senate.
The poll was conducted from Sept. 11 through Sunday.
The undecided voters will play a key role in deciding the race.
The poll showed 17 percent of Republicans, 27 percent of Democrats and 48 percent of unaffiliated voters as undecided.
