There are 2 days until very important votes and Warren hasn't endorsed the only candidate who is even close to her stated values. She stuck in the race when it was clear she couldn't win. Bernie supports are not happy with her for that and other reasons, so to see a video of her going on SNL yesterday and making jokes about not endorsing anyone it is infuriating. That is why people are upset with AOC for tweeting that clip and approving of it. That being said who the fuck knows where her supporters are going to go at this point. I imagine the ones who actually cared about the politics will go to Bernie and the rest of the white women will go to Biden.
