Remember, it was Spector that guided both Roberts and Alito through the hearings, was incredibly fair and hardnosed when necessary against the likes of Kennedy and others, and voted for both Alito and Roberts in committee. So don't be quite so quick to totally condemn. He's a loose cannon, indeed, but in the case of Alito and Roberts, he done good.
Spector = Specter. Freudian slip.
BRAVA!
You are correct; Specter blows hot and cold more than any other of the "moderates"; this is as opposed to Snowe, Collins and Chaffee who can usually be counted on to blow cold when the heat is on.
And he did the heavy lifting on Thomas too.
