% of Democrats in exit polls in PA: 2004, 41%; 2006, 43%; 2008, 44%. Democrats in PPP PA sample today: 48%.
Well, how much of that is due to overweighting of Dems vis a vis Republicans, and how much of it is due to Indys showing up in lower numbers overall, which wouldn't have the same effect? Did Geraghty compare R numbers?
To be sure, I don't believe this poll's top line, and there may be some D oversampling; but I do think the race is closer than it has been.
