It’s not a huge change, but Quinnipiac now puts Pat Toomey ahead of Arlen Specter, 43 percent to 42 percent. In May, when he flipped parties, Specter was up by 20 percentage points.

The poll also finds Obama’s approval/disapproval at its worst ever in Pennsylvania: 49 percent approval, 42 percent disapproval.

Also, the folk at Quinnipiac have room for some subtle jokes:

“Toomey and Specter are neck and neck in what could be a 13-month horse race. The challenger’s ability to close the 53 – 33 percent gap in Quinnipiac University’s May 4 poll is evidence that the longtime senator’s decision to switch parties to avoid a potential loss to Toomey in a GOP primary may not be the magic bullet for reelection that he had hoped it would be,” said Peter Brown, assistant director of the Quinnipiac University Polling Institute.
“Specter has more than enough time to reverse his fortunes, but being tied with the relatively unknown Toomey is evidence that this election has become a referendum on Specter.”

You caught the “magic bullet” reference, right?
