I've always liked him, but he really screwed up on this. I have to seriously question the judgment of a politician who calls someone a name, especially while they are campaigning and in front of a camera. Just stupid, and the guy was a minority too, that makes it 100x worse in the hyper PC world we now live in.
A bigot? No. A boob? Well, he could be. He very well could have 'Howard Dean screamed' himself.
What's to question? He called a Democrat hack a monkey. It's a non-issue. An apology isn't necessary.
I think he did all of us a favor by outing hisself as an idiot for saying that in front of a rolling camera. If he had the nomination locked up and THEN did it, it would have been much worse.
