Hard to know whether exit polling numbers have leaked yet (it’s coming up to 4pm East Coast US time), but Intrade has McCain an 89% chance of being Republican nominee, and Clinton and Obama both on 50%. Nailbiting.
(FWIW, I’m an Obama supporter. Here’s a review of his two books that I wrote for the SMH a year ago. Funny to think that then he was just a 1/5 chance, and that in mid-2006, he was a 1/50 chance.)
