Sestak to Obama: Can you send Michelle instead?

Holly Bailey

This may be the closest Joe Sestak comes to being photographed with President Obama before November. The Democratic U.S. representative told reporters earlier this week that although the president had offered to campaign on his behalf of his Pennsylvania Senate bid, he admitted he'd rather have First Lady Michelle Obama.

Why? The president's approval rating in the state has fallen 20 points since a year ago, and according to a Quinnipiac poll, 48 percent of Pennsylvania voters don't think he deserves re-election in 2012. It's not clear whether Obama would help or hurt Sestak, who is tied in polling with GOP opponent Pat Toomey.

Nationally, the first lady's 66 percent approval rating is nearly 20 points higher than her husband's, according to Gallup.
