The right accuses the Democrats of being radical left socialists, and the Democratic leadership responds by moving to the right. The powerful people you refer to - who do not want the progressive agenda to succeed - are the democratic leadership themselves. They work in tandem with those on the right to sabotage the efforts of progressives to gain power in the Democratic Party.

So yeah, I’m not part of the party, not by my own choice but because the party doesn’t want me. If you are truly of a progressive mindset it doesn’t want you either, but honestly it seems they’ve successfully tamed the progressivism within you.
