If Obama loses Pennsylvania, McCain has a good chance, agreed (although this election may end up with the blue and red states “trading paint”). But do you have any numbers to back up your claim that the Democrat base isn’t “united”?
If Obama loses PA, he has to win VA, which is unlikely.
As for his own support, the Polls have stated very clearly that he is only getting 83% of his own Parties vote.
Obama needed to have a massive turnout to offset those loses.
Or he needed to keep the GOP turnout depressed, which was the goal of these phony polls.
With a fired up GOP turnout, matching or exceeding 2004, Obama is going to be swept away.
PA is in play because Obama cannot unite the base and many Democrats are not going to vote for him.
