Really, Liberals do NOT want to throw the Progressives under the bus: They want to elect a President who will get changes (especially in the Supreme Court) that Progressives will like. They won't get the revolution, and they won't suddenly get to hunt down and barbeque the rich. But they will get a liberal Supreme Court for the next 30 years. They probably won't get single-payer for all, but they will get some movement towards it maybe including profit limits on Big Pharma. They won't get free college for everybody, but they will get some relief programs for student loans and some low-cost state colleges and universities for the qualified.
Why settle for the broken dream of changes that the American public will not support versus some changes that they will support? Politics is the Art of the Possible. Having dreams is great, but fixating on dreams that never come true is for losers.
