What has happened to Republicans that Donald Trump, after Super Tuesday, is their presumptive candidate for president?
Trump is revitalizing an old American political movement — populist nationalism.
Trump speaks for those deeply hurt by the rise of the left, who feel marginalized. Who resent that their country has been let down and trashed by the rich and the well-educated.
Trump can't be seen as leading established conservatives. He is a populist, not a conservative, and there is a big difference.
This new disposition of mostly white, middle-class and lower-middle-class Americans is a resurgence of an old theme in American life. We haven't called it "populism" in a long time. And rightly so, for it is the core of what was once called "Americanism."
Frankly, it is a kind of old-fashioned, 19th-century "liberalism" under which free markets and limited government are trusted to help individuals rise in life. The "liberalism" denotes individuals' liberty to make the most of their opportunities. That is the idea of America.
Trump and his supporters don't want to "conserve." They want change, not the status quo. They want to "win," not "lose." They want the good life and are willing to work for it, playing by the rules of free-market competition and bottom-up politics. They see themselves as the remaining true believers in the American Dream.
Trump's supporters echo the tradition of Americanism stretching back to the Puritans and the Revolution, to people who came to America seeking religious freedom or other personal opportunity or who were born here and understood the country to be open for growth and development and personal advancement.
