I find this suggestion by James Smith deeply plausible, echoing a point made by Will Davies last year that ‘free speech’ is becoming the unifying principle of a right-wing in the process of recomposition:

a successor conservative movement to Trumpism with appeal to many nominal centrists would be one that retains Donald Trump’s break with political correctness, his antifeminism, his Islamophobia. But which obscures those views by stepping up the culture war rhetoric about free speech and identity politics on college campuses (about which Trump cares little), while striking a slicker “evidence-based” technocratic tone.
