The top post (in general) seems to be a bit of a little known "secret". The Fox/MSM is more comfortable with making these things "Team D" vs. "Team R".
ANYone who thinks there's some sort of simple, overarching, and irrefutable "Constitutional Principle" at the heart of all this, is dreaming. A sufficiently motivated Court could easily find plausible Constitutional grounds for upholding OR overturning The PPACA. The problem...as I see it anyway though, is that overturning it portends so many downstream unintended consequences, that it's difficult to see how even this Court, might be sufficiently motivated to overturn it.
A similar, albeit DISimilar example might be, Bush v. Gore. There again - the Constitutional grounds were anything but obvious and plain. And, a sufficiently motivated Court could easily have decided either way. BUT...since Bush v. Gore was a one-shot deal, with virtually no implications for any other election prior or post, it was easy for The Court to side with Bush, since that decision essentially existed in a legal/Constitutional vacuum.
