No, he wasn't. He just lost his temper.
I did, too - all of the lies and nonsense Kerry was so glibly spouting was infuriating. I could scream at the tv and throw things, but Bush was supposed to remain calm. He didn't.
Bush was over-tired and under-prepared.
He ran out of material after 30 or 40 minutes.
That's the fault of his handlers, and you know it. Why are you resisting the obvious?
