Yesterday morning Trump was on Morning Joe, very bright and early. Mika and Joe asked how much sleep he got, having come directly from the debate to New Hampshire. He said, one hour and a half. He was doing interviews even after that yesterday, along with surrogates fanning out to programs also, and a rally last night and another tonight.
No one does that sleep deprivation well. It always shows.
His children need to kidnap him and lock him into his penthouse over the week-end with no phone, television or other means of communication with the outside world.
