How do you see the other side of the equation Gary?   Million of people believe whatever the President says.   Why?    I believe their's  a strong component of emotion in those followers.

I haven't decided if President Trump is by nature 1)  A good reader of people, a skill of salesmen and managers, and his statements are intentional and calculated manipulation of a crowd.    2) A seriously insecure person who has trouble balancing some significant emotional experiences with what I believe is a pretty good intellect.  

It seems he is not drawn to study/reading, but can be influenced with new information!    The President probably starts with the smallest knowledge base of politics as any President ever elected.   Hoover may be his only competitor.   Both entrepreneurial stars of their generation with no experience as an elected political leader.
