I don't understand PA but how can santorum fall like this?

Part usual cyclical rise and fall of support this far out, part excessive negative media coverage, part the nature of polling, but mostly his own stupid statements (such as during hurricane season trying to restrict public access to Nat'l Weather Service data.) Much of the damage is self-inflicted, but relatively little has to do with him supporting Specter (that's primarily conservo-utopian blathering that wouldn't move the polls much.)

That was a political payoff to AccuWeather in exchange for their bribes campaign contributions. It's a textbook example of the corrupt "crony capitalism" that has screwed up the post-Communist transitions of some of the old Soviet Empire states (most notably Russia itself).
