Anyone who has listened to the tapes of Nixon’s instructions to his aides knows that Nixon was a profoundly amoral and criminal man. He was not a good President, he co-opted the Left constantly as he had no conservative or moral scruples.
Pointing to the wickedness of Democrats does not change this. Charles Colson publicly repented of his Nixonian amorality, Nixon himself never did so.
To single him out as "profoundly amoral and criminal" is grotesque and totally misunderstands the reality of the political stage--Nixon never did anything that his predecessors hadn't done numerous times before--but got away with. Be honest--hang one, hang them all.
Compared to Kennedy, who is now openly acknowledged to have rigged the 1960 election; Carter, who attempted to enlist the aid of the Soviet Union KGB in tampering with the 1980 election; Clinton, who pretty clearly had political enemies killed; and Obama, who has committed treason by any reasonable definition, Nixon was a peach.
