Oh sure, it's now Trump's party. And the next Trump on the horizon is......................................well........ exactly who is the next Trump? There are none.
Trump is a one off. Many or most of the would-be Trumps who ran for congress in recent elections have gotten hammered.
The guy in Wisconsin, Nehlen, who ran a Trump-style campaign to defeat Ryan in the primaries lost 85-15. He was/is an anti-Semitic nut, so it's good he lost by a huge margin.
Trump rode the wave of immigration reform to the White House. Which I totally support. In fact, other than the tariff business and the juvenile tweeting, I support most of what Trump has done so far.
He won despite losing the popular vote by three million votes and the Dem candidate too lazy, smug, and arrogant to campaign in key Midwest states which Trump did not win by overwhelming margins.
In short, Trumpism probably ends with Trump. There are no populist Trump-type clones on the horizon.
