Sanders dropping out makes the situation very different - for (in actual life probably pretty small) "Bernie or Bust" crowd and their very vocal online buddies who are actually right-wingers pretending to be lefties and actual bots or Russian operatives. Back in 2016, they used "Bernie math" and pretended that the fight continued all the way to the convention, and that they were not helping Trump because they were fighting to make Bernie the nominee after all so he could beat Trump more easily than "Shillary."
What is their story going to be in 2020?
