I don't think he ever got over getting fired by Reagan (for the patsie worshippers, yes, he didn't get fired technically...he was simply moved to a windowless office and given no responsibilities until he took the hint and quit) or getting the conservative nod for president.
Look at his last campaign. He had double digit support when he started out, but as he became more desparate and appealled to every fringe, leftist group he could for votes, most of those who had admired him quickly walked away. They had seen the real pat buchanan and were disgusted at what they saw.
It's kind of a shame that he did this to himself. Ten years ago he was a conserative icon, today he is a hack footnote.
Edited for accuracy.
Some others are merely hack posters.
Well, I've got the "windowless office" part because of a space crunch -- now, how do I get the "no responsibilities" part? I promise to quit in, oh, fifteen years or so.... :-)
