The majority of voters in America are moderate, not far right or left. For all the candidates to support the person with the best chances of winning is called strategy. For you to claim that the DNC made that decision for each candidate is a conspiracy theory.
That is simply not true. Stop spreading misinformation. In addition I did not claim they made the decision for each candidate. What they did was run a first-past-the-post cacus that allowed candidates with conflicting interests to allocate their political weight against a clearly popular candidate. If they’d done ranked choice voting from the start, it would not be an issue, instead they allowed candidates (like Bloomberg) to spend millions, gather significant support, and then cast that support to a vastly unpopular candidate. You’re literally trying to argue Hillary was a good candidate with the best chance of winning but both polls, exit polls, and the caucus itself showed that not to be the case. Without the collaborative actions against Bernie by the other candidates allowed by the DNC Hillary would’ve never headlined the 2016 ticket.
But they didn’t do ranked choice. So for most of the primary it was Clinton VS Sanders. So we don’t know who would’ve won in ranked choice if all the other candidates stayed in. We only know that Sanders didn’t get as many votes as Clinton.
