all things considered, if sanders had won the important blue and purple states that he was supposed to win - maine, massachusetts, minnesota - then he'd be in a decent position, right now - because bloomberg came through and split the vote in the south.
it shouldn't matter if biden cheated or not, because sanders should have never ceded that much ground to buttigieg in the first place.
sanders didn't lose because of his policies, he lost because of poor tactical planning.
i've had a running commentary on this, and i hope it is useful to future candidates that run into this same problem of trying to find a way around these red states in the south.
