The blog Right Wing News
surveyed 100 right wing bloggers on this subject by posing the question: "Out of all the gangsters, serial killers, mass murderers, incompetent & crooked politicians, spies, traitors, and ultra left-wing kooks in all of American history — have you ever wondered who the worst of the worst was?"
Slightly fewer than half the bloggers (43) responded but their answers are I think a fair representation of Wingnut "philosophy". Here's the list:
23) Saul Alinsky (7)
23) Bill Clinton (7)
