It is unreasonable to expect him to become more reasonable more calm more cogent more coherent as he becomes MORE DESPERATE. Do you?

Important decisions are smacking him  down to size
Important polls (fox news) is showing him losing repeatedly by more than a slim margin
Important rallies are not being attended BY HIS OWN PEEPS which is humiliating him

What's left for him to do but go from town to town hat in hand seeking searching for rallygoers who will make him feel whole again. Nothing else he can do but that. Whatever happens as a result happens. No skin off his nose. His focus is on him his winning his numbers his size his importance his manner his his his his his his his his.Whatever occurs elsewhere does not concern him even though he may have caused it. That's YOUR problem.
