Doesn't he basically have to rely on the west? Even if he wins the SE it won't be by a wide margin like it was for him in the 80's or 90's but instead a few points. So he would need to at very least tie out west and I don;t see him doing that against a pro-life Democrat and a westerner at that.
I guess it depends on what we are defining as "relying" on the west. If an election is that close and the west is what Specter is looking to to save him, he's done.
what I am putting forward is the worst case scenario for the PA GOP. In which an eastern moderate Rep faces a Western Moderate Dem and the former is unable to win in the west b/c of the latters presence. The former faces a problem in that his margin will be lower then previous years in his base due to political shifts of that area. Lets say Specter won the SE by 5% how much would he need in the west to put him over the top? Can he get that with Wagner running against him.
