Thanks for clearing that up. So they will allow for time-wasting blathering by talking heads while Hillary shuffles off to a dark corner to get an injection of something.
Trump should be the gentleman or simply be respectful and either now or at start of the debate state clearly: “I have no problem with Sec’y Clinton sitting or taking a break. It is only right and fair that she be allowed to do so if needed. I’ll be happy to talk during these intermissions so that we have no dead-time on TV or cable.”
Let her sit or take breaks. The optics of making her stay or stand to the point of collapse would give her unneeded sympathy vote. The public will blame Trump even though it is not his decision.
