John F. Kennedy, who seized the White House from Richard Nixon in a frenzied campaign that turned a whole generation of young Americans into political junkies, got shot in the head for his efforts, murdered in Dallas by some hapless geek named Oswald who worked for either Castro, the mob, Jimmy Hoffa, the CIA, his dominatrix landlady or the odious, degenerate FBI chief J. Edgar Hoover. The list is long and crazy - maybe Marilyn Monroe's first husband fired those shots from the grassy knoll. Who knows?
