PA in Play?

Quinnipiac has released a new poll of Pennsylvania voters showing Obama losing ground to his potential Republican challengers. Mitt Romney now has a slight lead in that state, and other GOP candidates have also gained:

A majority of Keystone State voters now disapproves of the job Obama is doing as president. Just 43 percent of voters approve of his job performance, while 54 percent disapprove. That marks a significant decline from mid-June, when voters were split evenly on Obama.

Romney holds a 44-42 percent lead over Obama, reversing a seven-point edge for the president in June. Santorum now trails Obama, 45 percent to 43 percent; in June, he trailed by 11 points...

Obama also leads Rep. Michele Bachmann, R-Minn., 47 percent and 39 percent, and he also leads Texas Gov. Rick Perry, 45 percent to 39 percent.

In 2008, Obama won Pennsylvania by over 10 points, a margin greater than any shown in this poll.
