It seems pretty obvious to me at this point that the DNC would rather lose than have an actual progressive win.

It’s not in their interests to let a progressive win. Just like their counterpart, the DNC takes a shit ton of bribery donations from corporations lobbyists. Bringing in a progressive who would reform the system or push back against pro-corporate policies is biting the hands that feed them.

DNC should’ve started promoting someone else as Presidential candidate since the last 4 years and let Biden work quietly in the background.
