As long as he has been there, it is time to retire.
If he had the grace to do that, it would solve a lot of problems. An up and comer, moderate to conservative Dem could take the nomination and have a chance at the seat. If we end up with a ballot of Darlin' Arlen Specter vs. Santorum Lite Toomey we could very well end up saddled with the bastard again. And I might not even bother voting, since I couldn't in good conscience cast a ballot for either of those jokers.
Please vote, anyone would be better than this loser. at least you would have a better chance at getting what they say they are. this guy is a lying two faced rat!!! If cornered he changes.
