Notes About Health Care Ruling
As for the ruling, two things should be noted. First of all, it is clear that the mandate to buy health insurance means a reduction in the freedom of Americans. Secondly, it is however also clear that it is no more so than existing welfare state programs like Medicare and Social Security, where people are in effect through the tax system forced to buy health insurance and pension insurance for when they become older than 65. So if Obamacare is unconstitutional, then there wouldn't have been any reason not to consider Medicare and Social Security as unconstitutional, something that few leading Republicans would openly argue for.
As for the political impact, Mitt Romney is the big loser. Some argue that he is a winner because the health care insurance mandate is unpopular, but I disagree considering that he as recently as 2007 called it "ultimate conservatism" and has yet to renounce his old statements he simply has no credibility arguing against Obamacare.
