The best explanation I've heard for Bernie staying in the race is that he simply can't stop talking. I've read he was invited to leave a commune in 1971 because his devotion to talking precluded maintaining a work ethic acceptable to hippies. His career since seems to have been based on the primacy of talk over outcome. So as long as there are baristas willing to send him their tip jars to pay for the microphone, he'll keep talking.

I've heard the Sanders camp complain that Mrs. Clinton has only debated him three of the four times she had previously agreed to. In their innocence, they fail to see that a 25% discount rate on a Clinton promise is actually a pretty good deal. Honor does not come easily to someone who claimed to dodge Bosnian bullets which harsh facts revealed to be flower petals. I would disagree with jp1 that she sold her soul. It would be more accurate to say she has crowd-sourced it. I must admit the accountant in me is impressed by the tax-effective way in which she has monetized her prospective influence.

As a Republican, I hope Mrs. Clinton rewards Debbie Wasserman Schultz for her fealty. We Republicans have little enough to rejoice in this year, and any bone Hillary could toss us would be appreciated.
