Nixon also didn't have Fox News and a conservative attack apparatus as powerful as the modern one to prop him up. He was an asshole and war criminal but in terms of surface-level bullet point accomplishments that can easily be rattled off to simpletons he destroys Trump. Normalization of relations with China, the founding of the EPA, the Clean Water Act, various anti ballistic missile measures with the Soviet Union, troop withdrawals from Vietnam, and so on.
If Nixon had been elected in 2016 he would have cruised to two full terms and would be considered one of the truly great Presidents. He'd be an absolute god to Republicans and would have Reagan/McCain style respect from Democrats. That's not to illustrate that Nixon was good, but rather how fuged up our political discourse is and how bad things are.
