By any definition, Trump is not a classical populist. His traction derives from opposing unchecked and cynical illegal immigration, not diverse and measured legal immigration. And he is rebelling not so much against a flabby, sclerotic status quo as against a radical, even revolutionary regime of elites who are now well beyond accustomed norms. It is hardly radical to oppose the Confederate doctrine of legal nullification in more than 300 sanctuary cities, or a de facto open border with Mexico, or doubling the national debt in eight years, or ruining the nation’s health-care system with the most radical reconstruction in the history of American health-care policy, or systematically running huge trade deficits with an autocratic China that does not adhere to international norms of free trade and predicates expanding political and military power in the South China Sea on its commercial mercantilism. Trump seemed incendiary in the primaries, but as he is juxtaposed to the official Clinton extremist agenda, he will likely be reinterpreted increasingly as more mainstream — a probability enhanced by his selection of Mike Pence as his running-mate.
