Denniston told Yahoo News. "I think he was determined to try to uphold some key parts of the law, if he could find a way, partly because...he has grown concerned about the public perception that his Court is a partisan-driven Court."
He's concerned about public perception! That's a fine way to make a ruling. If he's going to rule based an outside opinion rather than the Constitution, why didn't he look at what the public WANTED, which was NO Obamacare?
Be angry at Roberts for his ruling - okay. But your comment (and a lot of other comments I've seen) is based on someone's opinion of why Roberts ruled as he did and not based on something that you factually know for sure.
