It is not over until it is over. Trump needs to pull the party together, and so far he has failed to do so. For someone so adept at "deal making" it seems he continues to overestimate his power in this situation. Like OPapaDoc, he seems to see himself as the king, and he expects his adversaries to come crawling on their hands and knees. Great leaders kill the opposition with kindness. So far, Trump shows no evidence of having that in him.
