For months now, Democrat Hillary Clinton and Republican Donald Trump have been sparring at each other from afar. On Monday they'll do it face to face, on a stage at Hofstra University on Long Island in New York.
Debates have been a mainstay of presidential campaigns, it seems forever. But that's not quite the case: The first general election debate didn't occur until 1960, in a Chicago TV studio, between Vice President Richard M. Nixon and Senator John F. Kennedy.
Monday's debate between Clinton and Trump will take place on the 56th anniversary of that first debate.
