I think that one important reason that right wing American populism is steamrolling post war progressivism is that the populists are at least able to give voice to contemporary anxieties and concerns whereas libs don’t even have any pretense of updating their ideological, social, and cultural ‘technology’ to start addressing the issues we face. The libs have a very profitable industry doing Potemkin reenactments of great mid century lib cultural and political victories to flatter the boomers, but that has come at the expense of being almost totally disengaged from the present.
