You mean when we lost by some 10% in the vote against Hillary fucking Clinton, a legendarily unpopular politician, with even socialist-hostile West Virginia protest-voting for Bernie over Clinton?

"But the DNC tipped the scales by showing favoritism", yes, they wanted a coronation, but it didn't come down to a handful of voters who were swayed by fucking DWS, it came down to Bernie not being able to overcome the long-standing nominee who had been building a ground game for her presidential run for... 16 years? Arguably more?

Bernie threw his hat into the ring as a protest, not expecting to gain much support. He had to build an apparatus from the ground up in a matter of months. That he got within 10% of Clinton is a miracle and a showing of the strength of Bernie's position - but also not a loss attributable to the sinister DNC mind-controlling millions of voters.
