Presidential numbers are ugly for Rick Santorum here in Pa, according to Public Policy Polling -- not only does he trail fellow Republicans in a hypothetical primary matchup, but he trails Obama too:

-Only 38% of voters in the state have a favorable opinion of him to 44% with a negative one. His numbers are particularly bad with independents whose ratings of him break down 30/54.

-Santorum trails Barack Obama 48-40 in a hypothetical contest, despite the fact that Obama's approval numbers in Pennsylvania continue to be under water. Most striking are a 20 point advantage for Obama with independents and the fact that he pulls 79% of Democrats while only 72% of Republicans are committed to Santorum.

-Most worrisome for Santorum are his GOP primary numbers though. The 54% of home state Republicans with a favorable opinion of him is well behind the 64% who like Mike Huckabee and the 63% who like Sarah Palin, equal to the percentage who like Newt Gingrich, and just a hair above the 52% who like Mitt Romney.
