Death penalty has to be voted on unanimously by the jury. If he doesn't get the death penalty, at the federal level he'll get life. Either way, he'll probably die in prison.
From what I've read from people who attended the federal arraignment, he was smiling, smirking at some points, and in general seemed happy. I wonder how long it will take for the arrogance to end. Will it be after he is locked up in his new home, a high securitypl federal prison? The media circus will end, <modsnip: unnecessary namecalling>, and that's when the reality may hit that he really blew it. He may realize that instead of enjoying life with his millions, traveling, having fun with friends and starting a family of his own, he's stuck in a concrete box and being told by some guard when to wake up, when to eat, when to work, and who he shares a cell with. IMO, that may be the point when he really regrets his decision.
