In the end, the KKK did not choose to support Donald Trump because he was a Republican but because they agreed with the ideas that he (and other far-right Republicans) spout.

Gonna have to disagree with you chief. That racism is all still there. Democratic racism is just more subtle. Start talking about building affordable housing/apartments or busing low income kids into their schools in a well to do liberal neighborhoods and they all turn into David Duke.
Case and point, Boston is as blue and liberal as they come but I guarantee you'll hear the nbomb there about as often and enthusiastically as you would at a Trump rally in Mississippi
