He has a good argument to make in Pennsylvania if he emphasizes Obama’s disastrous energy policy.
I am not sure the energy policy with the exception of gas is really hurting Pennsylvania. A lot of people are making big money on the fracking especially Western Pennsylvania where Romney COULD make inroads, but he should concentrate on VALUES! Social Issues would make Romney an easy pick for Pennsylvania but he does not talk much about them.
If he talks about how Obama wants to kill coal it could help him in northeastern PA, a moderate Democrat stronghold.
