I just don't get why we're not training and endorsing out the next group with all this press. Sanders and Warren need to back and/or start a coalition of progressive up-and-coming leaders that they can help hone and introduce to the larger political landscape while they have the energy and influence. They need to stop being the only torch bearers and start bringing in underlings. Idc if they follow them around like a posse, might actually be better if they did. I would cuddle with Sanders all night if I could, I'm just tired of his name being the only one catching attention. The will try to bury any movement with him when his time comes, best to get ahead of it so momentum can keep going.
Social Democrats will always cater to Liberals, because they both rest on the foundations of Capitalism. Social Democrats aren't trying to disrupt the system, but prod it towards more safety nets. Even if they raised successors, they would face the same struggles, because the DNC can't support itself without the blessing and support of the Bourgeoisie as their donors.
A truly destabilizing movement comes from outside the boundaries of the normal electoral system and depends on real, actual Worker Organization. That's why it's helpful to read theory. I wrote an introductory reading list for Marxism if that appeals to you or anyone else.
