Romney basically implemented Obamacare before Obamacare even existed in his own state. Had he won, he would have implemented it at the federal level. The only reason he was against Obamacare during the campaign was because he was running against Obama. ObamaCare by the way isn't that great, it's more of a kayak for private insurances than anything else and it benefits them more than anyone else, it's kind of yet another extra tax that benefits a few corporations.
