Then He Took It on the Chin.

Nixon only ran once for president, in 64. He did something that no president has, i don't think. In 68 he just knew he didn't have the confidence of the people any more. And so he made this speech where he said: I will not seek, nor will i accept my party's nomination for a second term as president. That's rare. Most guys just do it cause you're supposed to.
