For the next 20 years we're going to see GOP candidates attempting to copy the Trump formula and failing miserably.
I don't think a Pat Buchanan type who talks in calm, even tones about anchor babies and chain migration is going to do very well. You need to rile people up and get them really spitting mad, and say so many outrageous thing that the stone-cold racism just slips in among all the noise.
Trump is unique. No one else is going to be able to do what he did.
Yea, like fascism in Italy with Mussolini after he died. Fascism and Trumpism are dead in the water without their cult leader to whip the masses into a frenzy.
