This is almost too easy. Not only does this poll have Obama up 45-42 on Clinton, but it shows the two most important issues for PA voters are The Economy and The War. (These two topics were far and above the others; no other issue even broke into double digits in importance.)
PA voters also believe Clinton is the better candidate on the economy 48-41% and Obama is the better candidate on The War 50-38%.
Repeatedly tying Obama's strongest issue (his anti-war stance) to the war's resultant economic mess (undercutting Clinton's strongest issue) should serve him extremely well. Of course, Clinton will attempt to negate their differences on Iraq, while emphasizing her economic ideas.
In my opinion, Obama's argument is the far easier one to make--especially because he can supplement it with Clinton's longtime pro-NAFTA stance (and NAFTA's resultant effect on PA economy), which also undercuts the all-important issue of her "trustworthiness."
