This.

Dems, and maybe in this sense, "the left", are divided.

Berners are considered toxic to the party, ignored by media, and many party line Dems will smear and distract with "u r russian" BS, along with "u are why we have Trump" pretty much anytime there is a challenge from the left.

The divide is generally along economic lines too.

Big money has found out it can pretend to be "progressive" by favoring liberal social issues, sometimes to a fault. While at the same time, crushing the working class and poor economically.

Berniecrats, also say they are progressive, but are generally solid left economically. There are some harder lefties out there too, some like Bernie, but want more radical leftism. I digress.

The ones doing the censorship and general BS
