" he is very much a Quixote in that in his twisted logic, he really believes that he had been given a "divine dispensation" to lie, distort, smear and belittle anyone that doesn't agree with him.

That's very unfair to Don Quixote, who never went in for stuff like that. And even when he mistook some windmills for giants ("creatures of mass destruction" as you might say) he didn't send any else off to fight them, he did it himself. And that has certainly never been Bush's style.
