Karl Smith asks. Kevin Drum guesses Romney would repeal Obamacare. Tyler Cowen differs:

I expect Romney to claim he has repealed ACA, but in fact he will change five aspects of the law and cement the rest of it in place, albeit in a less progressive manner and with lower Medicaid expenditures. (Outright repeal actually would not be easy, not to mention filibuster issues.) He knows he doesn’t have any other “right-wing health care plan” in his back pocket, won’t be willing to restore the status quo ex ante, and he will be willing to take the “Tea Party knock on the chin” very early on in his term, hoping to repair the fence later. Ultimately letting the issue fester doesn’t help him, and he is smart enough to realize that.
