What, exactly, does the progressive wing want?
For my entire life (I'm 37) far-out liberal ideas included
-stop aggressively destroying the planet's ability to support human life;
-regulate industry to keep it from doing the above and to keep it from running itself into the ground
-make sure there are opportunities to get an education that will lead to meaningful work and won't punish your ambition by turning you into a lifelong debt serf;
-make sure that where there are opportunities to get rich, that these opportunities are more or less tied to doing something that is useful or at least not actively destructive;
-stop being a willing hostage to Middle Eastern dictatorships in exchange for the privilege of driving overpowered four-wheel-drive cockmobiles;
-extend full citizenship rights to all citizens, yes, even the queer ones;
-make sure that health care is available, yes, even to people who aren't rich.
Anyone who has taken these ideas seriously in the past thirty years has been labelled a liberal, a socialist or worse. It's only because the "center" has moved to such a ridiculous right-wing extreme that this could happen. Once upon a time, things like the New Deal were considered the center.
If these are centrist policies, then who needs liberals? Honestly--what more do you want?
