Also, thanks to senatorhatty for pointing me to this NY Times Article by Ron Suskind. (Registration is free and in this case quite worth it)

In the summer of 2002, after I had written an article in Esquire that the White House didn’t like about Bush’s former communications director, Karen Hughes, I had a meeting with a senior adviser to Bush. He expressed the White House’s displeasure, and then he told me something that at the time I didn’t fully comprehend – but which I now believe gets to the very heart of the Bush presidency.

The aide said that guys like me were “in what we call the reality-based community,” which he defined as people who “believe that solutions emerge from your judicious study of discernible reality.” I nodded and murmured something about enlightenment principles and empiricism. He cut me off. “That’s not the way the world really works anymore,” he continued. “We’re an empire now, and when we act, we create our own reality. And while you’re studying that reality – judiciously, as you will – we’ll act again, creating other new realities, which you can study too, and that’s how things will sort out. We’re history’s actors . . . and you, all of you, will be left to just study what we do.”

This provides a clue as to why Bush supporters believe things that Bush did not say, but wants them to believe, and why most of those people believe Bush said those things when he didn’t. Apparently Leadership means that they Lead you to believe things that aren’t true.
