Theory: Obama, the egomaniac that he is will forgo his liberal stances for a bid of popularity. The people that will hate on him the most during his tenure will be the leftists. This is not me approving of him. It's the farthest thing from that. It is just a prediction. He will do some highly liberal things, but I believe his narcissism will override many of his decisions.
Prediction: Troop Withdrawals will not happen, at least as he said he would be in favor of. He is no idiot. An all out retreat would be a disaster, he knows that. So if you voted on this idea of troop withdrawal now and forever, sorry.
