There's really not much difference between these things.
You get shades Trumpism from national level Republucabs as far back as Herbert Hoover circulating photographs of Al Smith dancing with black women. Nay further - there was a Republican Southern Strategy from about 1880 on the Stae level (the lily-whites etc.).
Reagan let himself be read as a libertarian ideologue ("To me, the heart and soul of conservatism is libertarianism") despite not being particularly libertarian about anything.
Trump didn't "destroy the neocons"; he elevated them to power and then shadowboxed them in public to retain his outsider appeal. None of this is real.
The Republican Party, like the Democratic Party, is a corporate brand. This is all it is. It represents nothing.
That's a pretty activistic way of looking at America's political parties.
