Mitt Romney heads to Michigan on Thursday where he plans to give a major speech on how to "repeal and replace" Obamacare.
Time's Mark Halperin says it's a smart move for the presumptive GOP frontrunner:
Romney's rivals believe health care makes him unnominatable. Romney has failed so far in convincing the media and others that he can explain his record on this issue. By putting out a detailed plan well before any of his opponents, Romney has his best chance to move the conversation from the past to the future. Hillary Clinton tried to do the same thing on Iraq in 2008 and almost succeeded; and/but right now Romney doesn't have anyone standing in his way for the nomination who is as politically formidable as Barack Obama was four years ago.
