I am not at all certain how Scalia will vote. He sold out his originalist principles in Raich, so it would not be that big a deal to go against his own opinion in that case.
Keep in mind that two of his protoges did uphold Obamacare based on his opinion in Raich. I simply advised you not to bet your lunch money. You're free to ignore my advice.
It seemed to me that your point was that Scalia might not rule against Obamacare because of this. I think that is ridiculous. Did you have another point?
