Watergate was good for American politics for a number of reasons. First, it got Richard Nixon out of the White House.

The public had a right to know what happened when Nixon tried to spy on his political rivals. Finally, Watergate saved America from further embarrassment brought to us by a bad president. It's good for the people to know what's really going on in government.
