From Daily Kos, it seems that even Sanders’ super watered down “endorsement” of Clinton was too much for some:

After giving the weakest of weak support for Clinton by acknowledging that he would vote for her in Nov, Sanders own revolutionaries seem to be beginning to turn on him.

“Disappointment of the century to witness Bernie Sanders telling that he supports Shillary. Run independent Bernie, you are the only hope. Trump rather then Hillary”

“What I want to see is you supporting Jill Stein over Hillary Clinton. Someone who actually has the same values your campaign did. No matter what you say, me and many others will never vote Hillary. At this point I don’t care if Trump wins. Anyone is better than Hillary.”

“I lost all respect for Bernie since he will vote Clinton…..are you kidding me
