I just don't support going after Chafee because RI is a bit of a lost cause. As far as party registration is concerned, Democrats there outnumber Republicans by nearly four to one.
Arlen is serving his last term. I don't recall Orrin straying too far off the plantation lately.
We had ample opportunity to depose Specter, but too many people were running around using your "let's not take out Chafee" argument. PA just reelected a "dead man walking."
As for Orrin Hatch, who also happens to be a native of PA, his problem is that (after 28 1/2 years), he's been in the Senate too long and allowed himself to get cuddly with the enemy. As others have pointed out, we don't send these people up there to make friends and participate in media circle-jerks, we send them up their to accomplish a "Conservative" agenda. We need more people who are unapologetic and bold in their political service.
