"The dead-seated hatreds of American politics flourished in the Trump years. He stoked them, and did not make concerted efforts to bring the country together. Nor did the Democrats. Trump felt deeply wronged by the Democrats who felt deeply wronged by Trump. The walls between them only grew higher and thicker. My 17 interviews with Trump presented a challenge. He denounced Fear, my first book on him, as untrue, a "scam" and a "joke," calling me a "Dem operative." Several of those closest to him told him that the book was true, and Lindsey Graham told him that I would not put words in his mouth and would report as accurately as possible. Trump decided, for reasons that are not clear to me, that he would cooperate. To his mind, he would become a reliable source. He is reliable at times, completely unreliable at others, and often mixed... But the interviews show he vacillated, prevaricated and at times dodged his role as leader of the country despite his "I alone can fix it" rhetoric. As America and the world know, Trump is an overpowering presence. He loves spectacle. In a time of crisis, the operational is much more important than the political or the personal. For tens of millions the optimistic American story has turned into a nightmare."
