Whither populism? Is the insurgency associated with Donald Trump and Sen. Bernie Sanders a flash in the pan, or is it something real The answer to that question, of course, depends on who does the answering. Most of the Republican establishment, along with the Democratic establishment—which some describe as the “Uniparty”—would prefer to believe that the populism of Trump and Sanders is temporary, that is, a nightmare from which they will soon awaken. Meanwhile, the Trumpians and the Sandersistas see themselves as part of a long-term force, even the winning force, within their respective parties. Yet now comes an author with an arresting argument: He believes that the Trump and Sanders groups, currently in different political parties, might yet find themselves fighting on the same side—perhaps even in the same party.
