Nixon was a real loser also
Not even in the league with lincoln, clinton and carter.
Nixon didn't have charisma. His other sin was to try to cover up the bad actions of his men. Compare his "sins" to clinton's or carter's.
Nixon was a geopolitical genius. Nixon tried to prevent people like the Clintons from gaining power. He used a lot of the same tactics that JFK did ( now in the pantheon of great men becuase he was assasinated ) He was correct about the internal enemies of the USA. Nixon's problem is that he was uncomfortable with his demons. Contrast this to Clinton who was very comfortable with his demons and was a MUCH bigger crook.
