Those numbers contradict an AP/Yahoo poll released earlier Wednesday that showed more voters viewed Michelle Obama negatively than positively.

According to the new poll, 51 percent of registered voters report a favorable view of the presumptive Democratic presidential nominee's wife while 28 percent hold an unfavorable view. Just over 21 percent did not express an opinion.

Meanwhile, 39 percent of registered voters hold a favorable view of John McCain's wife, Cindy, while 23 percent report an unfavorable rating. The poll also shows she is considerably less known than Mrs. Obama - nearly 40 percnet report having no opinion of her.

"Don't read anything into the fact that Michelle Obama's favorable rating is higher than Cindy McCain's - Obama's unfavorable rating is higher than McCain's as well, and both of those measures are simply due to the fact that Obama is better known than McCain," CNN Polling Director Keating Holland said.

The poll, conducted on June 26-29, surveyed 906 registered voters and carries a margin of error of plus or minus 3.5 percentage points.

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.
