We end up with a Nixonian Dictatorship/Dystopia ala Watchmen until he dies... after that, who knows?
Haha yes, the idea that the nation would be "better off" if Nixon was never caught is one of the most hilarious ideas ever. More than likely, conservatism would take a more outright fascist approach than the faux libertarian-conservatism that happened under Reagan.
I predict someone will call this hyperbole, let me explain later.
I don't think you're necessarily wrong, but I'm interested in hearing anyways.
