In March 2016, when few political consultants, pollsters, data-jockeys, psy-ops masterminds or media maestros thought that Donald Trump could or would ever win the White House, I assessed his rise differently in a long Salon essay that few can read now because Americans barely glance into what we always call "the rear-view mirror."

History is more than a rear-view mirror. It enables people who give it more than a quick glance to know that someone like Trump surfs a tsunami of ressentiment — a public psychopathology in which gnawing insecurities, envy and hatred, nursed by many in private, converge in scary social eruptions that present themselves as noble crusades but that diminish their participants even in seeming to make them big.

"Ressentiment's gloves really come off once there are enough angry 'little-big men' to step out en masse, with a Sarah Palin or a Glenn Beck," I warned nearly five years ago, adding:

Trump is leading them across the Rubicon, signaling that he'll mow down anyone and anything in his way. Legitimate grievances that fuel ressentiment sometimes drive its eruptions to a fleeting brilliance, as when Palin tapped currents of thwarted love and hope in her speeches in the 2008 campaign. But, like her public persona, such gestures soon curdle and collapse, tragicomically or catastrophically, into their own cowardice, ignorance and lies.

But now that those predictions have been book-ended suitably by Susan Glasser's "Obituary for a Failed Presidency" in the New Yorker, her summary of Trumpian ressentiment prompts me to a couple of quick observations.

First, Americans need to do more than glance into rear-view mirrors as they speed to nowhere. "The past is never dead. It's not even past," wrote William Faulkner, novelist and interpreter of the American South. meaning not that we should impose the past upon the present but that we should learn from it as we see it at work in our lives. Non-historians should acquire the pleasing habit of checking History News Network summaries and links to op-eds and magazine essays by historians and occasional interlopers.   

Trump couldn't have conned as many of us as he did if our schools had taught more of us about this country's dalliances with demagogues like Huey Long and Joe McCarthy. The invaluable program "Facing History and Ourselves" now guides thousands of students in doing what its name commends. We need more of it.
