Thinking objectively, maybe the Hillary supporters in the remaining states should vote Bernie in the primary. People (including me) used to be very skeptical of Bernie. But now Bernie turns out be stronger than Hillary in the general election. Bernie can defeat Trump, Cruz and Rubio by a larger margin than Hillary. And very very very surprisingly, Hillary would actually lose to Kasich while Bernie would still beat Kasich. IMO, to maximize a democratic win in the general election, the democrats in the rest of the states should vote Bernie.
