In a New York Times has an article about how the wealthy donor class of the Democratic Party is colluding with the party leaders to take down Bernie Sanders.
This isn’t exactly secret, but this quote pretty much explains the whole scene in a remarkably vivid way:
From canapé-filled fund-raisers on the coasts to the cloakrooms of Washington, mainstream Democrats are increasingly worried that their effort to defeat President Trump in 2020 could be complicated by Mr. Sanders, in a political scenario all too reminiscent of how Mr. Trump himself seized the Republican nomination in 2016.
The whole “Ancien Régime” vibe is vivid, and it is appaling.
