We’re a long, long way from 2020, but it’s abundantly evident that Trump will again run a Nixonian campaign, tearing down his opponent and presenting himself as the champion of an aggrieved coalition that Nixon called the “silent majority” and Trump calls “the forgotten men and women” of America.

Consumed by internecine battles and the idea of opposition, Democrats run the risk of again nominating someone like McGovern who pleases progressives but steers a course too far from the country’s center of political gravity to win, even as Trump continues his funhouse mirror impression of Nixon as the avatar of white cultural-grievance politics.
