Is Obamacare Unraveling? And if so, how much damage with it do before it does?

Here's a piece saying Obamacare is unraveling. He points to cost overruns, unpopularity with the public and problems it might be facing at the US Supreme Court. Given our debt problems and the unworkability of the government now controlling more directly our nation's health care system, it's days are ultimately numbered. The only question is how much damage will it cause in the interim. I suspect a lot.
