Word of the day to describe the Bush administration: Manichean.
Manichean: adj - Of or relating to Manichaeism; dualistic.
Manichaeism: n - The syncretic, dualistic religious philosophy taught by the Persian prophet Manes, combining elements of Zoroastrian, Christian, and Gnostic thought and opposed by the imperial Roman government, Neo-Platonist philosophers, and orthodox Christians.
"This Manichean mentality not only drives George W. Bush personally, but it also consumes our political discourse almost entirely."
