There are some other things transpiring in American politics right now. But we must note that Democratic leaders are now unabashedly stating what Bernie Sanders supporters said over and over in 2020: the party pushed Joe Biden primarily to stop Bernie.
The article is kinda BS. Nobody admitted to any wrongdoing. They simply “admitted” that party elite support coalesced around Biden to stop Sanders. You may think that sucks, but there’s nothing unethical about it. That’s how coalitions in politics work.
