The slow coalition of party elites backing Biden when the primaries are clearly showing that Bernie is the preferred candidate is reminiscent of the 1944 Democratic convention. Let me explain.
At the 1944 Dem. Convention, delegates from across our nation were shouting "We Want [Henry] Wallace" for VP. Wallace was an ardent defender of the New Deal and a staunch believer in wage and racial equality. Wallace was also overwhelmingly popular. See below. 
Party elites had other ideas. They devised a plan to take down and stop Wallace. What exactly happened is detailed below from 2 books. Fake fire hazards. Explicit orders from higher-ups. Blocking supporters. Bid-rigging, Getting alternative candidates to run to dampen support. 😱
Just as Wallace encountered in 1944, party elites and members of the establishment want to stop Bernie as they see him as a threat as a real possibility that an individual who wants to actually enact substantive change will obtain a position of power.
What scares me is that, should Bernie get the nomination, will party elites chose a nuclear option of encouraging/facilitating Bloomberg to run as a third-party option simply to ensure that Bernie will not win. The fact that I am even contemplating this scares me too.
