* He has exposed, by inscribing it in action and speech, the hypocrisies of the academic multiculturalists, who to the Trumpists, not to mention libertarians, embody a self-censoring authoritarian language that does not allow rational thinking to take place.
* He has pointed out the true extent of unemployment (it is said of the European neo-populists that they arose in the face of permanent unemployment, a phenomenon French and German thinkers call "civilisation du chômage," or civilization of unemployment), which mars, above all, the African-American and Hispanic zones of habitation in America's cities, landscapes of apocalyptic misery that have received no recognition from the neoliberal masters; he's right when he asks African Americans, "What have you got to lose?"
* He is a crude simplifier, but he has described, from the other side of the political spectrum than Sanders, intractable problems with the neoliberal conceptions of trade, modernity and empire. He seems far less interested than Hillary Clinton, for example, in starting a confrontation with Russia in the Middle East.
Once upon a time the Clintons took over a Democratic Party, insecure about its electoral prospects at the national level, and converted it from the inside into something it never was before: a party of neoliberal elitists, beholden to a new moral righteousness among a rising professional class, uninterested in the problems of poverty, no longer recognizing the working class let alone doing anything to help it. This time Trump has started taking over a Republican Party that was working smoothly with Clintonian Democrats for a quarter century, managing to steer its supporters toward a path not questioning the hollowness of multiculturalism but heading them off in a parallel universe of Christian righteousness.
All that is over now. Electoral firewalls seem like firewalls only until their last manifestation, and in retrospect seem like flammable tinder; had Trump been allowed to talk about the issues, and nothing but, even if in his authoritarian way, and had he had the discipline to pivot quickly to his message despite being baited, the Democratic midwestern firewall, for example, might have crumbled. In any event, Trumpism is here to stay; what will the neoliberal elites do next?
