Perot was ahead of the curve concerning NAFTA and international trade by at least a decade.
The problem with Perot was Perot. He turned himself into a cartoon caricature on Larry Kings show with the whole chartboard schtick and he had an unfortunate Texas twang nasal quality to his voice.
The problem with Perot is that the American people then, and still to a great extent now, prefer smooth-talking, media-approved crooks over an honest but unpolished man.
This is a massive flaw in the modern American character.
