Engaging a little hyperbole on your own. I see. ;)
Dean usually does the following:
Uses insults and mockery toward the President
Hints at his prior drinking in a derogatory way
Insinuates that he is stupid and lazy
Talks about his "cronies" (such as Cheney) in an insulting manner
Makes fun of his Texas upbringing
All of these elements are here in Ann's column. Sounds pretty Deanish to me.
