Ukrainians use the term “political technologist” as a favored synonym for electoral consultant. Trump turned to Manafort for what seemed at first a technical task: Manafort knows how to bullwhip and wheedle delegates at a contested convention. He’s done it before, assisting Gerald Ford in stifling Ronald Reagan’s insurgency at the GOP’s summer classic of 1976. In the conventions that followed, the Republican Party often handed Manafort control of the program and instructed him to stage-manage the show. He produced the morning-in-America convention of 1984 and the Bob Dole nostalgia-thon of 1996.

Given Manafort’s experience and skill set, it never made sense that he would be limited to such a narrow albeit crucial task as delegate accumulation. Indeed, it didn’t take long before he attempted to seize control of the Trump operation—managing the budget, buying advertising, steering Trump toward a teleprompter and away from flaming his opponents, appearing on air as a primary surrogate.

The genesis of Donald Trump’s relationship with Paul Manafort begins with Roy Cohn. That Roy Cohn: Joe McCarthy’s heavy-lidded henchman, lawyer to the Genovese family. During the ’70s, Trump and his father hired Cohn as their lawyer to defend the family against a housing discrimination suit. (Cohn accused the Feds of using “Gestapo-like tactics.”) But Cohn and Trump became genuine pals, lunching at the Four Seasons and clubbing together at Studio 54. It was Roy Cohn who introduced Stone and Manafort to Trump.
