Everyone knows how J.D. Vance reinvented himself for the Trump era—going from the NPR-listening public's favorite "hillbilly"-whisperer—and frequent Trump critic—to the president's favorite lapdog (not to mention one of the world's most prominent ideologists for the new wave of radical right populism/white nationalism/neo-fascism sweeping the globe).
Once it became clear that white supremacism and Nazi-curious Groyperism were the hip new thing in the Republican party—and the fastest way to rise in Trump's political movement—Vance had no trouble abandoning his earlier assessment of Trump as a "demagogue" and adopting the new far-right "nationalist" talking points as his own.
