Eleanor Clift is by no stretch a conservative apologist, but her reporting in Newsweek on the Specter switch exposes an angle that the broadcast networks are omitting: the Machiavellian maneuvers behind-the-scenes to coax Specter to jump the GOP ship.
Of particular interest is Clift's revelation that Gov. Ed Rendell's motive for pushing Specter to become a Democrat was to shut down a potential Democratic rival for the U.S. Senate, Rep. Joe Sestak (Pa.) [emphasis mine].:
Those who know Rendell say he really wants the seat that Specter holds but would not run against his friend. The scenario that was unfolding had Specter losing in the Republican primary to Club for Growth President Pat Toomy, the favorite of Pennsylvania's conservative Republican base, and then had Toomy losing to a Democrat in November 2010. The Democrat suiting up for that task was Rep. Joe Sestak, a retired Navy admiral in his second term, eager to move up, and at 57 years of age, young enough to stake a claim on the seat.
A Sestak candidacy would derail Rendell's future plans. Keeping Specter in the seat at his age, which is 79, makes it far more likely that the seat would open up in the kind of timetable Rendell would hope for.
[...]Whatever Rendell did to get Specter to this point, their political futures are now inextricably bound together. And if there's any politician you want on your side in a knife fight, it's Rendell. He is the closest thing to a ward boss in Pennsylvania. He can clear the field for Specter, gin up the enthusiastic support and help raise the kind of money Specter will need. And then, in due time, it will be Rendell's turn.
