Quite surprised. In fact I swear I read that it was overturned shortly before reading it was upheld.
I consider it a good thing. I found the plan the Democrats came up with too weak to be comparable to the universal healthcare of other developed nations. A public option and non-profit basic care were things I desired, and while I know there was no chance in hell of this happening, abolition of medicare and medicaid would be crucial as a cost saving measure. Still, there aren't a hell of a lot of ways to provide universal health care, and the way Canada and Taiwan do it (with the single payer insurance) seemed acceptable. Had this been overturned it would have probably cast away any hope of a universal healthcare system.
I'd still rather have the Bismarck model though...
EDIT: Incidentally, I hate discussing whether or not healthcare is a right. I don't know, I don't care. There's no reason it should have to be a right for us to provide it.
