Obama weak in Pennsylvania

PPP reports:

Pennsylvania is looking more and more like it could be a tough hold for Barack Obama in 2012. His approval rating in the state continues to be under water at 46/48. More voters have expressed disapproval than happiness with Obama on all three polls PPP has done in the state so far in 2011. And even though Obama took Pennsylvania by 10 points in 2008 the best he can muster right now in a head to head match up with Mitt Romney is a tie.

If Obama can't win Pennsylvania , it's hard to see how he'll win in 2012.
