The whole thing will get shot down. I remember one of the justices saying if you think I’m going to read it, you’re nuts. He just said it better.
I think that was Scalia, and his point was that the Court will not and should not be responsible for going through the bill line-by-line to determine what is salvageable and what is not; in other words, if the mandate is overturned, the whole house of cards should collapse and Congress needs to start over.
