In a nutshell

the reason Pubs are fighting the Affordable Care Act ISN'T because it won't work, but precisely because it WILL and that will wreck their agenda of killing gov't services that the rest of the world has and loves. Really simple when you think about it, as in this snippet passed on by Dave Hardy.

Liberals favored health reform both because it would work and because it might enhance their ability to push for other policies; conservatives were and are determined to kill health reform even though it would work — in fact, precisely because it would work — because it would weaken the rest of their agenda.
