Roberts is the asshole that upheld the Affordable Care Act. He changed his vote overnight, looking sweaty and uncomfortable while he did it.
Someone has pictures on that guy. He is bought and paid for.
He is. And one interpretation is that, in doing so, upheld the longstanding tradition that the Congress makes the laws and that, unless it is clearly unconstitutional, it stands. I'm not taking that side (or any other on that issue in this thread) but it can certainly be argued that his decision was actually one of the most conservative, though not neo-conservative.
