Donald Trump’s research revealed that the people wanted someone who was not complicit in these failures and who had built and run something. Washington, Jackson, the Harrisons, Grant, Theodore Roosevelt, Eisenhower, and others had risen as military heroes, though some of them had had some political exposure. Jefferson and Wilson were known as intellectuals, Madison as chief author of the Constitution, and Monroe and John Quincy Adams as international statesmen. What is called for now is a clean and decisive break from the personalities and techniques of the recent past. Donald Trump doesn’t remind anyone of the presidents just mentioned, but he elicited a surge of public support by a novel, almost Vaudeville, routine as an educated billionaire denouncing the political leadership of the country in Archie Bunker blue-collar terms.

Last (Super) Tuesday, he completed the preliminary takeover of the Republican Party. He demonstrated his hold on the angry, the fearful, and the ashamed by passing the double test: he had held no elective office, but he was a worldly man who knew how to make the system work and rebuild American strength and public contentment. All the other candidates in both parties were vieux jeu, passe. Only a few of the governors (Bush, Christie, and Kasich) had run anything successfully, none of them had built anything, and all were up to their eyeballs in the sleazy American political system — long reduced to a garish and corrupt log-rolling game of spin-artists, lobbyists, and influence-peddlers. Bernie Sanders gets a pass, but he is an undischarged Marxist, and while many of his attacks on the incumbent system and personnel have merit, his policy prescriptions are unacceptable to 90 per cent of Americans.
