Granted, the 79-year-old president had been up all night or almost all night, a fact evident in part because he took a 4:30 a.m. call on his mobile phone from my Times colleague Tyler Pager. Anyone in Trump’s dress shoes would be exhausted. But his bearing and his cadence suggested something more than a mere sleep deficit, as did his inability to sound triumphant as he claimed another triumph, to flash much color as he peacocked. At a moment like that, you’d expect there to be enough adrenaline pumping through him for a pumped-up performance. Instead he delivered a wound-down one.
