From Michael Wolff’s"Fire and Fury", which you can believe or not believe, but sounds like a likely scenario.:
Shortly after eight o’clock that even when the unexpected trend – Trump might actually win – seemed confirmed, Don Jr. told a friend that his father, or DJT as he called him, looked as if he had seen a ghost. Melania, to whom Trump had made his solemn guarantee, was in tears – and not of joy.
There was, in the space of little more than an hour, in Steve Bannon’s not unamused observation, a befuddled Trump morphing into a disbelieving Trump and then into a quite horrified Trump. But still to come was the final transformation suddenly. Donald Trump became a man who believed that he deserved to be and was wholly capable of being the president of the United States.
