While it's true that Arlen Specter was probably more responsible for sabotaging his nomination than any other Republican, you can't really fault him.
After all, no one ever seriously considered Arlen Specter anything other than a Philadelphia Republican, i.e. a liberal Democrat.
But Warner's vote against him lends the leftist witch-hunt against that remarkable jurist a retroactive aura of legitimacy, which allows historians to claim that he was a "judicial extremist," and tar him with other blatantly false calumnies.
-good times, G.J.P. (Jr.)
I do hope that Warner will retire after this term.
