A portion of the GOP base is animated by racism. It’s less than 1% of the GOP, but if you parse the words this was not quite a lie.
In contrast, about 90% of the Democrat base is animated by racism - Dem base (somewhat more so than Dem voters and far more than GOP) tend to be blacks who hate white, whites who hate whites, and whites who despise blacks and think the only way blacks can get by is with government help.
Case in point: My first boss was an Amherst grad from patrician Virginia. He mocked my conservatism and preference for Goldwater (it was 1963). When he took his vacation that summer, he went to Mississippi and served as a Freedom Rider -- an action that I admired.
However, upon his return, he came to the office flustered. Well, angered, actually. He told me that his landlord had allowed "a dirty n-word" to rent the apartment next to his. And he moved out, forthwith.
My admiration declined. And I gained some insight into the liberal mind...
