The Dolchstoss myth that’s sure to take hold if Trump is impeached or quits under pressure will be virulent. The tale his devotees will raise their children to swear by will describe the nefarious way that coastal elites, partisan Democrats, the liberal media, and a whole slew of other pseudo-Americans—from Muslims relishing our surprise introduction to sharia law to transgender weirdos, man-hating feminists, and America-hating Obama zombies, not to mention pusillanimous establishment Republicans—all conspired to deprive them of the greatest president ever: the only one they felt ever spoke for them. There will be talk of armed insurrection. Aspiring Dylann Roofs will look for an enemy headquarters to shoot up. It will be ugly.
