It’s odd that Hillary left the stage at all. Either she didn’t prepare herself for an hour or so on stage or something unusual happened to her.
Actually, to argue with myself, maybe many of the candidates take offstage breaks during commercials.
But it shouldn’t have run beyond the commercial break. Was she really held up by someone else in the bathroom? Did her staff know she would not go into a bathroom unless no one else was in it?
Maybe she fell asleep in one of the bathroom stalls, and they had to wake her up.
