In the 2007-2008 congress Specter, no doubt in part as a token of appreciation for that AFL-CIO support, was the lone Republican to back EFCA. If he votes for it again this congress, it’ll be tough for him to win the primary. But if he votes against it, I think he’ll find it tough to win the general election when his support from Democratic-leaning interest groups vanishes. I doubt Specter will avail himself of this option, but the obvious solution would be to stick to his guns on EFCA and follow up his support for the stimulus by switching parties and, like Jim Jeffords, reposition ideologically somewhat. In other words, stop being a vulnerable moderate Republican and become a plain-vanilla Democrat with a safe seat. It would be pretty easy for Specter, as a Democrat, to beat GOP nominee Toomey in a general election. But beating Toomey in a primary without becoming too right-wing to carry the state will be tough.
The Republican Party is driving itself off a cliff, and trying to make Specter the first one to go "splat" on the bottom below -- but he clings to his spot in the car all the same, even taking his turn at the wheel at times. Why? What is so compelling about that "R" next to his name that he'd rather risk political death than make a simple party switch?
