McCain's Uphill Battle in PA

"If you look at cold hard numbers, in order for McCain to win Pennsylvania, he is going to have to win at least 15% of the Democratic vote, 95% of the Republican vote and 60% of the independent vote. We believe McCain is losing independents by about 20 points right now in Pennsylvania, so he would need a 40 point swing." -David Plouffe, Obama's campaign manager.
