Conway, the campaign’s manager, was in a remarkably buoyant mood, considering she was about to experience a resounding, if not cataclysmic, defeat. Donald Trump would lose the election — of this she was sure — but he would quite possibly hold the defeat to under six points. That was a substantial victory. As for the looming defeat itself, she shrugged it off: It was Reince Priebus’s fault, not hers.

She had spent a good part of the day calling friends and allies in the political world and blaming Priebus, the chairman of the Republican National Committee. Now she briefed some of the television producers and anchors whom she had been carefully courting since joining the Trump campaign — and with whom she had been actively interviewing in the last few weeks, hoping to land a permanent on-air job after the election.

Even though the numbers in a few key states had appeared to be changing to Trump’s advantage, neither Conway nor Trump himself nor his son-in-law. Jared Kushner — the effective head of the campaign — ­wavered in their certainty: Their unexpected adventure would soon be over. Not only would Trump not be president, almost everyone in the campaign agreed, he should probably not be. Conveniently, the former conviction meant nobody had to deal with the latter issue.

As the campaign came to an end, Trump himself was sanguine. His ultimate goal, after all, had never been to win. “I can be the most famous man in the world,” he had told his aide Sam Nunberg at the outset of the race. His longtime friend Roger Ailes, the former head of Fox News, liked to say that if you want a career in television, first run for president. Now Trump, encouraged by Ailes, was floating rumors about a Trump network. It was a great future. He would come out of this campaign, Trump assured Ailes, with a far more powerful brand and untold opportunities.

“This is bigger than I ever dreamed of,” he told Ailes a week before the election. “I don’t think about losing, because it isn’t losing. We’ve totally won.”
