Could Bernie Sanders be signaling a pivot in his full-throated support for Hillary if she's the nominee? For months he's been saying that if he doesn't prevail in the primaries, he will support Clinton against Trump and URGE HIS SUPPORTERS to as well. That's caused a lot of angst here and been the source for many well-thought out diaries. It has spawned the Bernie or Bust movement and been the subject (and scorn) of many establishment pundits, and used as attack fodder among Clintonistas.
