PA may end up being as close as OH, especially with the hurricane having a much bigger impact there.
Of course, I'm going to be very skeptical of any polling from PA from here on out.
Dont count on it (referring to there being major effects in PA from Hurricane Sandy). My parents and brother are in SE PA. Sure, they got hit, but the area will definitely recover by Tuesday as I can tell from talking to them (my parents are without power, but surviving...hah). Keep in mind there is no early voting there.
Now, your comment about polling is true, though. You have the largest area of the state (SE PA) lacking power in many places, so it might be a bit difficult to find people to poll. So I, too, would be a bit skeptical of polling out of PA in the next few days.
