I don't always agree with Howard Dean. In fact, I still dislike him on a number of fronts since 2003. But he is making some good points, as are the people still supporting what is left of the health care bill, whenever Megolmaniacs Lieberman and (Ben) Nelson are done adding new provisions to make it even worse.
It makes one wonder if these two members of the Democratic caucus are doing this for political posturing for reelection, preening self-importance, or desire to make the bill so unpalatable that party stalwarts like Kerry can't stomach the final product. Another possibility is they want to show their superior power to that of say Brown or Sanders.
Principle clearly has nothing to do with it. Nelson said nothing about abortion until Stupak. Joe was for Medicare expansion before Liberals said it was better than the public option. Niether nixed Medicaid expansion until now.
