One the one hand, it’s going to be tough for Henry Waxman and Nancy Pelosi to paper

over the fundamentally opposing demands of the Congressional Progressive Caucus and the Blue Dogs. Rep. Paul Grijalva (D., Ariz.) tells the Post this morning that the compromise “completely cripples the public option.”

On the other hand, when push comes to shove and there’s a final bill before the House, I have a hard time imagining that any House Democrat wants to be the one who cast the decisive vote that meant it didn’t pass.

The one possibility that holds up any version of ObamaCare is if the Blue Dogs go home at the end of the week and find their constituents overwhelmingly opposed to what’s in the bill.

UPDATE: Cincinnatus makes the case that when you get right down to it, most Blue Dogs are nowhere near as conservative as their rhetoric or coverage would suggest. Their ACU ratings vary quite a bit, but most land in the 20s to 40s, with the average at 29.
