Nixon by all accounts was a good person and excellent statesmen.
Watergate happened because he realized that Americans and News Media care more about the photogenic candidate like Kennedy than who gets results.
Nixon would've just served out his second term and retired if he didn't get caught.
Ironically, News Media has gotten more blood thirsty and war like since Vietnam due to the thirst for juicy info on the war front. With exception to Engels, Cooper, and Hansen, everyone in News Media are just sports broadcasters.
