You know that Bernie lost the primary because the DNC cheated for Hilary, right?
Yes those documents were leaked by Russians. But they still existed. (Mostly, at least.)
The entire primary set up also is pretty biased. We don’t know how Bernie would have done outside a couple states because most states never got a primary vote.
Further, Hilary was soft amid the same people that were passionate for Bernie.
He might’ve been “boring” but he actually had a chance at winning and the DNC decided to fuck that up.
