@izzythepush,
Yes, he finally ended a much bloodier war than Iraq or Afghanistan, took him long enough. But his criminality was about stifling dissent. If Nixon had just taken payoffs like his Vice President, Spiro Agnew did-Agnew received a suitcase full of money for highway construction kickbacks from his days as Maryland governor in his White House office-we might shrug it off as a personal failing to be balanced against whatever good things might have been accomplished on his watch.
But Nixon was about putting dissenters in jail. He had a White House enemies list to use various levels of government to "screw"-Nixon's word-certain people he did not like. Among these were antiwar activist Jane Fonda, but also Joe Namath of the New York Jets, who wasn't politically active at all but had sort of a counterculture lifestyle for a football player. One person on the list, an educational spokesman who opposed some aspect of Nixon's education plan, wrote to the New York Times that he was surprised he was on the list because even though he opposed one aspect of Nixon's plan, he actually voted for Nixon in the previous election. And Nixon had this guy on the "screw him" list.
Nixon really was a tinpot dictator, the country would have been in much safer hands if he simply was crooked.
