The truth about him.
I disagree that Nixon’s first term was a success, domestically, unless by that you simply mean that he accomplished what he set out to. His policies were hardly conservative — he introduced wage and price controls, and the double nickel speed limit, the idiotic bane of my youth that wasn’t really undone until we got a Republican Congress in 1994. But I agree that the impeachment mood was driven far more by personal dislike for him than actual guilt. Bill Clinton got away with many things, and worse things, that Nixon was merely accused of. His primary crime, if it was one, was hiring ethically-challenged aides. It is interesting to speculate how much better off the Vietnamese would have been if he had been president in 1974.
[Update a while later]
I celebrated Nixon’s resignation at the time, but I’d been raised to hate him by Democrat parents. But the Clinton administration was when I finally turned my back on the Democrats as irredeemably corrupt and partisan. Nixon was hounded out of office, with the support of members of his own party, who found his behavior rising to the level of high crimes and misdemeanors, even though he was probably innocent of any actual crime. Clinton, on the other had, had his party circle the wagons around him, even though he had committed multiple federal felonies, after taking an oath to see that the law was faithfully executed, in the service of seeing that a young woman over whom he had great power and was sexually abused by him, didn’t get a fair trial, and sending out his winged monkeys to trash the reputations of her and other women that he raped and molested. There were a few honest Democrats in that episode, but the vast majority of them were disgusting partisan hypocrites, never to be taken seriously again.
