You are getting some pieces of the puzzle but not the whole thing. It is in all these people's interests to have "not Bernie" as the nominee because of the policies and worldview and ideals that his movement represents. Yes, they would have been fine with Pete or Kamala or Amy or Beto or Booker or Warren as their avatar. Yes Bloomberg would fit in fine or Biden and even Trump if it comes down to it, just not Bernie is all that matters. They stacked the field to see who would stick and it came down to Biden so they went with that. All the other candidates could just be seen as Biden surrogates in the end since they were quick to ditch any ideals and just went with Joe when they were told.

And all this is not because of Bernie the person, he's by far not the ideal candidate, it is the millions of people and activists and grassroots organizations that surround him they are afraid of. They are trying to keep those people out and keep themselves in. That is the complete puzzle.

They even told on themselves, for example here with ‘Stop Sanders’ Democrats Are Agonizing Over His Momentum
