Boy Do I know. I live in a city that has been socialist since 1979, but the community is trying to change that, we voted in three council members in the last election to represent the residents more, or at least they are trying.
I don't know if it would interest you but I found a google book that shows step by step how they did it. And I'm noticing a lot of similarities to what the Democrats are trying to pull now. I'll leave a link in case you're interested.
