@blatham,
I was there. I was (still am) a Bernie fan. I totally supported him, all the way. He was evidently better than Clinton, but he also knew that Trump was immensely worse than Clinton. So he did what he had to do for the greater good, he campaigned for her, as he had promissed he would if he lost the primaries. This guy Bernie, he's no joker.
Some people adopt a politician for one season, when it suits them, and abandon him the next, out of convenience. Bernie deserves better than that.
