When Nixon resigned from the Presidency, did he have any supporters remaining, or was the general consensus that he he needed to go? Any special or documentary I’ve seen about the subject always paints Nixon as a criminal who abused his power, and I’ve never seen anything to show that any politician or the general public still viewed him in a favorable light at the end.
In one of Glenn Beck's books, he cites that his father supported Nixon at the time (Beck was young at the time) to his shock. When he asked his father why he did, he simply said, "They're all liars." According to Gallup research from the time (taken from here), his father was one of a very small minority of the nation, although on the day of his last approval rating, his approval rating was at a dismal 24%. Striking though, is that the no opinion option shot up from 14% in July to 23% on his last poll, which suggests that at least a third of the country (since his disapproval rating was at 66%) had no ill will toward him (or not enough to say that they didn't like the job he was doing).
According to a Harris poll, a majority of their respondents believed that Nixon should not have resigned as a result of Watergate. My guess is that a President stepping down from office "volunarily" was unheard of at the time (with Washington choosing not to run for a 3rd term being the other sort-of case) and would've been treated in like manner of Pope Benedict XVI resigning as pope.
I hope this answers at least part of your question.
A former mod, /u/The_Alaskan, had a good response to the question: Did Richard Nixon have apologists in the press throughout the Watergate scandal? If so, did those journalist lose credibility after Nixon resigned? which might be a helpful way into the topic matter. Hope that helps!
