I'm not sure how many brain-dead people are on this list. Heartless, sure, but not brainless, however much I disagree or even despise a few of these folks. Donald Rumsfeld may be Satan, but he's not a drooling redneck either. Bet his IQ's higher than yours. Maybe even mine. :-)
(Although there are a few braindeads on the list--Dan Quale? I'll give you that.)
