Ignore all the batty, bigoted, just stupid shit he says and watch how he carries himself. Of all the supposedly great leaders running for the GOP nod, not one can wipe the smug off his face. He is winning, because he has the air of a winner. He projects strength and confidence and he panders openly to the worst instincts of conservatives. He's pretty good at a GOP primary is what I'm saying. On the debate stage, he is the only one that doesn't look like he's chewing on a turd, he looks like he just sold the other guys turd flavored gum and got them to pay for it.
Interestingly when he is attacking other Republicans his attacks are accurate, and sharp. When he is attacking the issues of the day he just says whatever silly shit he wants as long as it sounds tough.
