Nixon was another one who was taken down by Fake News. If you read the actual records there is nothing there that he actually did. If he would have stayed for the trial he would have won.
All-in-all, Nixon actually was a pretty damn good president -- especially when viewed alongside some of the more recent ones of Ford/Carter/Bush/Clinton/Bush/Obama. He had a lot pinned on him that he didn't deserve. If you listen to any lefty, the Vietnam war was his, like Kennedy and Johnson didn't exist. No mention that it was he that got us out of the damn thing.
Nixon was railroaded out on some pretty flimsy misdirection. Was he paranoid? Yes. Was he vindictive? Yes. That's not enough to get rid of a president, any more than it was to get rid of Obama.
