(CNN) - John McCain has the backing of Connecticut's Democratic-turned-Independent Sen. Joe Lieberman, but a new poll out Wednesday shows the state is decidedly Obama country.
According to a new poll from Quinnipiac University, Barack Obama is leading McCain in the state by more than 20 points, 56 percent to 35 percent. Much of that lead stems from the Illinois senator's 16 point advantage among independent voters in the state. He also pulls in 16 percent of Republicans there.
Connecticut has long tilted Democratic in presidential elections, and recent Republican White House hopefuls have often spent few resources there. It voted for John Kerry in 2004 by a margin of 10 points, and for Al Gore in 2000 by a 16 point margin. CNN considers the state's seven electoral votes safely in Obama's column.
The poll also provides further evidence that Lieberman, who bucked his former party late last year by endorsing McCain, holds little sway with voters in his home state when it comes to the presidential election. Even if McCain chose Lieberman as his No. 2, a prospect that most political observers agree is highly unlikely, only 14 percent of Connecticut voters said they would be more likely to vote for the Republican ticket.
Lieberman also appears to be hurting his own approval rating in Connecticut as he increasingly becomes one of McCain's most visible surrogates on the campaign trail.
Watch: Lieberman touts McCain
In a Quinnipiac poll released earlier this week, the Connecticut senator's job approval rating stood at 45 percent, the first time his it has dipped below the 50 percent line in that survey. Sixty-two percent of Connecticut Democrats now hold a negative view of their party’s Democratic vice presidential candidate.
