Do you have any idea how liberal Specter will be if he is reelected? He'll be too old to run again. His wife is a prominent Democrat and I wouldn't be surprised if he switched parties anyway if he wins the election.
Are you forgetting that Specter was the jackass who stood on the floor of the United States Senate and invoked Scottish law by voting "not proven"?
I for one would rather have a democratic senator than Specter as a nominal republican heading up the judiciary committee. Count me in as another Pennsylvanian for Toomey.
