A senior campaign official and Clinton confidante has told me that there will be a Democratic nominee by June 15. He could not bring himself to say the words "Hillary will drop out by June 15," but that is clearly what he meant. I kept saying, "So, Hillary will drop out by June 15," and he kept saying, "We will have a nominee by June 15." He stressed what a reasonable person Hillary is.

Everything about our conversation implied that he had already had this reality-based discussion with Hillary. He said the Clinton campaign plan is to collect as many votes and delegates as they can right through June 3, then take no more than a week or so to make their case to the superdelegates. Nothing he said indicated that he actually expected the superdelegates to move to Hillary in the week after the final election. The Clinton campaign has not lost its grip on reality. Yes, Clinton spokespersons publicly seem to be lost on gravity-free planet Clinton, but privately they know the end is near.
