This tells me that Obama knows the decision, which is that the SCOUTUS will uphold Obamacare. This will give him bragging rights of providing universal coverage AND that he faced down the white man's court. He'll go down in history as the baddest brotha evah.
Obama is a racist Communist egomaniac but he's not stupid and he wouldn't be getting into the face of the SCOTUS unless he knew he held the winning hand.
If they allow him to get away with it, then only an act of God can stop him.
OR the losing hand. This could well be just an attempt at damage control. As others have posted, the pi**y demeanor is a major clue.
