Lauren, you are not “the left”, nor do you speak for the left. Bernie’s hypothesis is that there is a great progressive non voting population out there who will turn out for a legitimately progressive candidate (him). The primaries will test this hypothesis. I’m predicting that he is wrong, but if he is right either he or Warren will get the nomination and I will work for them. “Progressives” need to understand that ALL of the candidates for the Democratic nomination will advance the progressive agenda, and the most progressive candidate will not necessarily advance it the furthest. Or of course we can form the circular firing squad and set the cause back even further…
