For some reason there are certain people in political life whose (in)fallibility is of supreme importance, both for their supporters and detractors. On THE LEFT I used to see this a lot with Noam Chomsky, with people who liked him saying things like, "I haven't ever seen him be wrong about anything," while his detractors would point to any little mistake as proof he was a tremendous liar bent on the destruction of the United States and perhaps THE WORLD.
