Charles, you might remember that the reason the GOP took racists in was because their gullibility could be exploited in support of an economic agenda to free greed from all moral and legal restraint.
For all the crocodile tears from the GOP over Trump his overt catering to that gullible base is all that keeps them in the party.  The GOP never actually intends to roll back the Civil Rights Act or establish a Christian theocracy and those people are finally figuring it out.
