I thought that maybe the internals were showing a closing, because Obama started radio advertizing first. Without that, I'd completely ignore PA.
You said that PA was very close and that, while you predicted Obama would win, you woudn't be surprised at all if Romney carried the state.
He said something along the same lines in 2008 when McCain decamped there and also pushed the same narrative in 2004. It's usually all to do with the turnout in Philly which he get's wrong each time.
I couldn't, and frankly still can't, figure out the emphasis on PA, in either election.
Going into Pittsburgh, because of the bleed over into OH, I can understand.
