I'm not prepared to concede the notion that some of the rhetoric that's been popping up is populist. Somebody else, who has never shown any regard for workers, has never fought on behalf of social justice issues, or making sure that poor kids are getting a decent shot at life or have healthcare.
In fact, have worked against, Economic opportunity for workers and ordinary people. They don't suddenly become a populace because, They say something controversial in order to win votes. That's not the measure of populism. That's nativism. Or xenophobia, Or worse. Or it's just cynicism.
