Baucus’ big complaint has not been with the bill itself, rather with the implementation of it, which is what he has characterized as a ‘train wreck.’
The implementation is part of what he voted for and contributed to. Too darn bad that he didn't think things all the way thru.
And as stated upthread...when the loyal minions discover that it ain't free for most people and they will be penalized for not having insurance...or worse yet their employer cuts them to part-time to avoid the benefit..all hell might very well break loose.
That, imho, is why he is fleeing his position and probably moving to Costa Rico.
