Trump's self-congratulatory speech was full of egregious lies, over-the-moon promises, and the usual load of vague bullcrap about how AMURRICA is only great if he's in charge. In other words, same old same old. His lackeys were all in attendance; Vance was smiling goofily; Melania was trying very hard to hide beneath her hat.
But the whole stupid ceremony lacked energy. Trump didn't babble for nearly as long as he usually does. His followers and stooges clapped when ordered to, but there just didn't seem to be any enthusiasm. Maybe buyer's remorse is already a thing.
