I'm pretty sure I have my memory straight, shortly after Nixon's re-election (but maybe it was his resignation) the campus cinema had a double feature: Nixon's Checkers speech followed by 'Dr. Strangelove.' And in that time period, multiple showings of Costa Gavras' 'Z'.

Charismatic? Many Nixon Loyalists were willing to commit crimes for him, so he inspired something in them. Of the many books that came out of the Post-Watergate period I only read one, but it was memorable: G. Gordon Liddy's 'Will'.
