There is quite a bit more than a snowballs chance in hell that Bernie will support Clinton before the primary is over:
“Sanders in recent weeks has made clear he aims to take his candidacy past the elections on Tuesday, when California, New Jersey and four other states vote. But the debate within the campaign indicates that Sanders’s next move isn’t settled.”

I guess I’ll ask this question again when Bernie gets behind Hillary before the convention.
