Steve M. from No More Mister Nice Blog has a particularly intriguing take on the mind set behind Bush's being taken by surprise by Kerik's "foibles," and by extension, how this illuminates the black-and-white thinking of conservatives in general:
(snip)
So Bush didn't get either one of them.
In 2000, he looked at Rudy and saw a guy whose marriage was crumbling, who was openly engaged in adultery, and who was being mocked in the press for it all. Yet Rudy had a reputation as a tough guy. How was that possible? In the eyes of a Bush, a man with personal problems, especially personal problems he can't keep secret, is weak; how can a weak man also be a tough guy?
Kerik, by contrast, clearly was a tough guy when Bush got to know him. A tough guy can't possibly be weak, can he?

I don't think conservatives are stupid. But I do think conservatives tend to see the world as black and white, good and evil. (I think most conservatives would admit that, and cite it as a virtue.)
A tough man is a steadfast man is a man of virtue. That's the myth of the cowboy; it's the myth of Bush in the eyes of his conservative base; and it really might be what Bush himself thinks. If so, no wonder he couldn't believe Kerik had any serious scandals in his life -- how could an ex-narc who's done buy-and-busts be anything but virtuous? I recommend reading the entire post -- it provides some new insight on some things that have been hard to understand.
