Based on the recent polls, Obama appears to be pulling away in Pennsylvania with an RCP average now at +5.5. Despite his gain in national polls over the past week, though, most of the other toss-up states appear to be pretty much as close as ever. The most surprising thing to me is that both the recent North Carolina polls are Obama +2.
