Any leftist politician that submits to capitalist rulers is not a leftist politician.
There is no “left” in America, Bernie is proof of that.
What have they got on Bernie
Bernie is using this opportunity to wring out some false promises from Biden. When Biden still loses the popular takeaway of that will be Biden lost because he moved too far left.
Biden should be acting now, but of course he won’t, because the wealthy who control the parties would rather see the world burn in a nuclear hellfire than see any progressive policies become law.
