The Pennsylvania Senate race between Republican Pat Toomey and Democrat Joe Sestak is currently tied, according to a new Quinnipiac poll of registered voters. The good news for Sestak, who defeated incumbent Arlen Specter in the primary, is that the trend is moving in his favor. A previous Quinnipiac poll of the race in April had Sestak trailing Toomey by eight points, and a poll in May had him two points behind Toomey.

Quinnipiac 7/6-11
Sestak 43
Toomey 43

Wouldn’t vote 1
DK/NA 12

Currently, both candidates have net favorable ratings. But for both candidates, roughly half of registered voters don’t think they have heard enough about them to make a judgment one way or another. That means both candidates have significant opportunity to define themselves and their opponents.

President Obama could be a potential drag on Sestak in Pennsylvania. Among voters, 46 percent approve of his job performance as President and 49 percent disapprove. The President’s numbers in the state are much worse on the nation’s top issue of the economy. Only 40 percent approve of how he is handling the economy, with 55 percent disapproving.
