Yup. Methinks Sanders is still in the race because he expects Hillary will exit for reasons.
Much harder to beat, because he actually _believes_ his rhetoric. She’s just saying whatever to get elected ... and like a dog chasing a car, won’t have a clue what to do with the Presidency should she get it. He, however, will turn us into the Soviet Union Mk. 2.
Alas for Sanders, there's little chance of that happening. It will either be Hillary vs. Trump or Biden vs. Trump (if Obama can figure a way to get rid of Hillary without allowing her to bring him down too in the process).
The DNC powers-that-be no more want Sanders being their flag bearer than the RNC powers wanted to see Trump in that role. The difference is that the RNC still has sufficient remnant of honor that they won't stoop to open fraud and mayhem to maintain their hold on power. The DNC is under no such constraints.
Bernie would EO/EM us all into bankruptcy. It’s why the GOP will do nothing on Hillary’s email issues, and quietly do plenty to help her.
