Jim Antle says that Massachusetts health care is still a problem for Romney:

Nevertheless, it seems to have hardened into conventional wisdom that health care is a non-problem for Romney. This is based on little more than Rick Perry’s dip and Romney’s recovery in the polls. Health care may not keep Romney from winning the nomination. Immigration, opposition to the Bush tax cuts, and numerous other sins didn’t sink John McCain in 2008. But the main reason Romney’s early frontrunner status has been jeopardized by a revolving door of conservative challengers, some of whom were virtually unknown on a national level before running against Romney, ought to be a sign that Mitt has problems.

I’m not sure that anyone has argued that it is a “non-problem.” Many conservatives and others took it for granted early in the year that Romney’s health care record was obviously fatal to his candidacy, and that was clearly not correct. Some people may be making an over-correction in arguing that it isn’t going to hurt him at all, but I haven’t seen it. I maintain that it is a liability, but it is not significant enough to deprive him of the nomination. The key reason for this is that he supports repealing federal health care legislation. Back in May, I likened Romney’s support for repeal to Obama’s opposition to the Iraq war. What I meant by that was that all that will matter to most primary voters focused on this issue is that he is against the administration policy they reject, and they will not be terribly bothered by the inconsistency or compromised nature of Romney’s opposition. Obama wasn’t reliably opposed to military interventions, but he opposed the one in Iraq, and that was good enough. Romney isn’t reliably opposed to technocratic domestic policies, but he is opposed to this one, and I suspect that will be good enough for enough Republican voters that he can win them over with his economic revival theme. I also doubt that very many voters otherwise willing to support Romney are going to throw up their hands in disgust at the mention of a state-level individual mandate.
