Well, one Republican. Roberts. The other four dissented.
Interestingly, he rejected the commerce clause argument and said that the penalty qualifies as a tax. I guess I can get behind that -- I still have a sort of gut opposition to the idea of the government forcing me to buy something from a private industry that happens to be corrupt as fuck, but when you start talking about taxes it becomes easier to remember that, oh yeah, the government already does that ALL THE TIME.
There's something in there about a narrow ruling on the Medicaid expansion but I haven't seen it parsed just yet. Other'n that the whole thing seems to be pretty much upheld. Which on the whole is a good thing. My reservations about the mandate aside, it's the best option we've got right now and if it had been thrown out it might have been another generation before we had another shot at any kind of healthcare reform. This, at least, is a start.
