6Donald Trump may be gone from the White House, but the 75 million people who voted for him are still out there . . .

Updated to reflect election results, this is a look at the entirety of the Trump phenomenon, using psychological and social science studies, as well as polling analyses, to understand Donald Trump's followers, and what they will do now that he's gone.

To find out, John Dean, of Watergate fame, joined with Bob Altemeyer, a professor of psychology with a unique area of expertise: Authoritarianism.

Relying on social science findings and psychological diagnostic tools (such as the Power Mad Scale and the Con Man Scale), and including exclusive research and analysis from the Monmouth University Polling Institute (one of America's most respected public opinion research foundations), the authors provide us with an eye-opening understanding of the Trump phenomenon -- and how it may not go away, whatever becomes of Trump.
