As Jonathan Chait notes, there are several proposals out there which could tweak the Affordable Heath Care Act in ways that would eliminate some or all of the saner Republican objections to it. As he further notes, Republicans are so fired-up to repeal the whole thing, so determined to score an "all or nothing" victory on this one that they'll never go for those proposals. I did a Tweet the other day that I still think is not as silly as it may look at first glance. It read, "Solution to health care dilemma: We repeal Obamacare, then Repubs pass the exact same thing but call it GOPcare. Everyone happy."
