What they should do is put sunglasses on the president so that no one can tell if his eyes are open or not. Then, you have a couple of aides carry him around and move his arms and legs for him. Someone could talk to people as the president, but only from the other room or around a corner, maybe while he’s facing away from them sitting on a couch, that way they can’t see his lips and won’t know it’s not really him talking. Just spitballing here.
