I don’t have every answer. (And I certainly can’t force any democrat to do anything.) The one thing that has worked is building local networks. If there are homeless people in your area get to know them, work with your neighbors to help them with food, (or in my case using my mailbox) find out who the worst cop at the nearest precinct is and help file complaints. Show up at school board meetings and co-op board meetings— talk to who isn’t being talked to amplifying what they say.
