Will the Democratic Party unify under Hillary or split in two

[Onlooker]

28. Some Bernie supporters are socialist, not social Democrat ...

... They will go off into the wilderness of useless votes and trivial movements, failing to form meaningful coalitions, and just sitting around with people like themselves having little if any impact on elections. But, most Bernie supporters are liberal or democratic socialist. They are interested in coalition building, and respect the voices of those who support Hillary, many of whom have better progressive and activist credentials than any Bernie supporter. They may not agree with the Hillary supporters, but in the end they will stand with their brethren and vote Democratic.

We can't worry about those who will leave the Democratic Party. But, that said, my guess is that the poll simply shows the pain of loss by Bernie supporters, and if the same poll is conducted in a few months, the results will be significantly different. Some people when they lose, lose gracefully, others don't. Some in the Sanders movement will see all the good they've done win or lose. For others, it's just a sports game, and they lost and are pissed off.
