I was directed to this story about George W Bush's use of abusive, emotive language as a political tool from the blog called Eschaton. (Another link I posted over a month ago referred to his whole behaviour pattern as "dry-drunk syndrome", which fits in very well with this kind of character disorder.) What's really good about this article is that it ends up by offering language tips to Democratic opponents on how they can counter the toxic effects of the President Unelected's speeches and sound bites.
