When Donald Trump announced his candidacy for the Republican presidential nomination on the morning of June 16, 2015, there was little indication the event would alter American political history. Pundits dismissed Trump’s chances. He was polling at 4 percent; the head of Fox News, Roger Ailes, suggested Trump was really seeking a job at NBC, not the White House.
But Trump did make an impression on Steve Bannon, a voluble conservative activist plotting his own takeover of the Republican Party. Watching the reality-television star deliver remarks from the Trump Tower food court to a crowd that allegedly included actors who had been paid $50 to hold signs and cheer, Bannon couldn’t contain himself. “That’s Hitler!” Bannon said. And, as Jeremy W. Peters writes in this spirited new history, “he meant it as a compliment.”
