What Makes Trumpers?

Young readers may not recognize this scene from 1975’s “Blazing Saddles,” where the black dude has been appointed the new sheriff of a town on the western frontier.  The bigoted white folks are extremely resentful, and here, the amiable town drunk is consoling him:

What did you expect? “Welcome, sonny?” “Make yourself at home?” “Marry my daughter?” You’ve got to remember that these are just simple farmers. These are people of the land. The common clay of the new West. You know… morons.

Coincidentally, an old friend asked me recently what I believe makes up the Trump base.  I replied that a Trumper needs to be in one (or both) of two groups:

a) The extremely unintelligent, and/or

b) Those whose brains are wired, either via genetics or lived experience, to be indifferent to the needs of other people.
