How did America end up with a leader who acts so crudely and despotically, and counter to our democratic principles? Why do his followers stick with him, even when he acts against their interests? To fully understand, John Dean, a man with a history of standing up to autocratic presidents, joins with Bob Altemeyer, a psychology professor with a unique area of expertise: authoritarianism. Together, using psychological diagnostic tools, as well as 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 what we may be able to do to stop it.
