Bush Supporters Speak Out

This writer at the libertarian Lew Rockwell site has a charming chronicle of how Bush supporters have responded to his criticisms of their man. The insults and abusive language are familiar, but what is so striking about the right-wing rabble when they get aroused is their penchant for armchair psychologizing to demean their opponent. My own armchair psychologizing leads me to suspect that this is largely projection, that these folks attribute petty and base motives to their opponents because those are the ones with which they are most familiar. Anyone not in an armchair have better insight?
