Aggressive primaries for D pols who don't hold the line for justice and human rights or who don't act in the interests of non-wealthy citizens. Re-establish boundaries within the party to bring its goals back to what they were in the New Deal and Civil Rights era. We had political dominance then.

I genuinely see the takeover of what was supposed to be the "left" party by politicians who are wealthy and business-connected as the first step to where we are today and we won't be able to walk it back until we start there.
