Many political strategists seem to think that a rough gubernatorial election in New Jersey will make vulnerable Democrats waffle on supporting healthcare. If somebody is going to vote against any Democrat who voted for the healthcare bill, there’s a pretty good chance that they’ll vote against any Democrat period. So a Creigh Deeds style healthcare waffle would be a pretty brain dead thing to do. But our politicians do a lot of brain dead things, so I wouldn’t put it past some of them.
If a congressperson genuinely opposes a bill, they should vote against it. Or maybe they should sublimate their wishes to the clear wishes of their constituents. Being passionate and genuine will get you a lot further than having somebody in the media label you “centrist”. Democrats lose a lot of elections for being lame. And there are few things more lame than trying to place yourself smack in the middle of an imaginary spectrum.
