Are Centrists Sabotaging Their Home State?

Yglesias is cynical enough to think it's possible:

Ed Kilgore reads an Arlen Specter op-ed and develops a hypothesis that might do something to explain how it is that the Senate “centrists” zeroed-in on the most-effective element of the stimulus package for elimination: “A cynic might observe that all of the four senators that Arlen Specter identifies as the organizers of the ‘centrist’ coup-by-amendment–himself, Ben Nelson, Susan Collins and Joe Lieberman–happen to come from states where the governor is of the other party.” Ed’s no cynic, I guess, but I am and I think this is important. I suppose it might be too cynical to suppose that the Gang of Four is deliberately trying to sabotage their states’ opposite-party governors. But at a minimum, you have to think that if there were political allies sitting in the relevant governor’s mansions that these legislators might have taken their calls and listened to good sense.
