I often ask the Nixon bashers what he did wrong-the answer is invariably "a burglary and some kind of illegal campaign practice". That's it. If you ask if he was a good guy or bad guy, they can talk for hours, but factually, the cupboard is bare.
I think Ben Stein is a great speechwriter. Too bad he couldn't write a speech for Nixon to get him out of the Watergate mess. Here's some info that the press "made up" in order to get the great Nixon thrown out.
