Progressive ally? Biden was literally the candidate that the establishment put their full force behind (including having Obama make calls to have other candidates drop to back him) in order to defeat Bernie in 2020. Biden himself said “nothing would fundamentally change”. A couple bones thrown here or there doesn’t change that. I don’t know if democrats are astroturfing here of all places or people are just deluding themselves into thinking he’s doing more than he actually is, but he’s really not.
