There was no one happier than I when Nixon resigned. I considered him a villain. I was a democrat at that time, and foolishly believed that what the media told me was true.
Thirty years of experience have taught me that a great deal about what we were told about Nixon was exagerration and fabrication. Did he break the law? Yes. Did he resign? Yes. You can speculate about his motives, but the fact is that he resigned to spare himself, his family, and the country an impeachment trial.
Bill Clinton didn't have that much consideration.
Nixon could have rightly challenged 1960's presidential election too.
