I think the main point made was that the chronic dishonesty and CYA of the bushadmin helps to foster the conspiracy theorists. That's a point which makes me hate the bushadmin even more. It makes the task of eliminating wacky conspiracies from the lexicon of the left all the more difficult. Hmmm...
I disagree with much of the stuff at the link in the first bullet point, but the article is great as a whole, imo.
