Thinking back to 1992, Ross Perot didn't brook any 'critisms'. He was a decent protest vote (althought the net effect was the awful Clintons), but he would have been a terrible President.
I have to agree, a President must have political know how, connections. The best thing about President Bush is he's intelligent enough to know that he doesn't know it all, he puts the right people in positions and lets them do their thing.
IMO perot didn't really want to be president. He got what he wanted, he sank President GHW Bush.
