Shaming establishment dems won’t work. You just have to primary them out with a better, actually progressive candidate. As more and more progressives get voted in, the establishment dems will be forced to lean further left just to get elected so that they can collect their corporate bribes like the republicans. Eventually establishment dems will either 1. Give up 2. Switch to being (outright) republicans or 3. Move only as far left as they have to be to get elected
