Law says what it says. Up to Congress to fix. Not up to the Court to re-write the law to make it constitutional. May be an unlikely result, but one that avoids constitutional issues.
If they go that way, a Chevron analysis starts with the language. If the plain language is clear, then game over. Period. That is how one of the lower courts ruled against the PPACA.
No one seriously thinks Kagan, Sotomayor, Breyer, or Ginsburg to against the government’s position. And good money is that Alito, Scalia, and Thomas will vote against the government’s argument. I think most of use are on the same page there.
I’m just not sure the government can count of Kennedy or Roberts to rule their way. Most discussion I’ve seen seems to focus on those two as being the most likely to cast the deciding vote(s).
Kennedy ruled with the three die-hard conservative on key issues in the prior PPACA case. Only Roberts saved the administration’s bacon there. And in the words of ThinkProgress, Kennedy’s vote “would happily blow up our entire health care system simply to lash out at President Obama’s signature accomplishment, forcing millions of Americans to face uncertainty, financial ruin or potentially even death after they suddenly lose their ability to access affordable health care.” i would not bank on him having seen the light now.
And there was much speculation that Roberts’ vote was a late switch, only after the taxation issue won him over. I don’t see such an out here.
