Poll: Pennsylvania sours on Obama

A poll released Tuesday shows that President Barack Obama and Republican primary front-runner Mitt Romney are in a dead heat for Pennsylvania's vote if the election were held today.

"President Obama’s approval rating in Pennsylvania has deteriorated to the point that there is no state he hopes to win next year which sees him worse," the Democratic Party-affiliated Public Policy Polling wrote in Tuesday's analysis.

Mr. Obama's 42% approval rating in the Commonwealth marks a 9 point decline over the past five months.

"That puts the state and its views on the president in league with tough-to-win states like Missouri and Montana, both of which Obama’s campaign played in in 2008, but neither of which he won, and neither of which he will likely win next year," the group wrote.

In a one-on-one vote, Mr. Obama defeated all potential Republican nominees except for Mr. Romney, who split the vote with the president at 45 percent each.
