Here is a plan I like:
Step one - Regroup and storm. We need to have infighting until a new left leaning populist movement emerges that can defeat this right wing populist movement. That requires folks to argue, bang their heads, retreat, and emerge anew. Accept the infighting for a bit.
Step two - rally around a new message. The message needs to be emotional, simple, and economic. It needs to undermine this administration entirely, exploiting their economic weakness. The policy should be reduced to a three word chant, with each word being a single syllable. Think about the simplicity and rhythm of "Drain The Swamp" or "Build The Wall," but imagine a good message that builds the economy for the masses.
Step three - back the most charismatic politician who adopts the message at every level of government.

Children have to learn/develop empathy. It's ok that you lacked it at one point. It's wonderful you have it today. Never listen to anyone who says it's a sin.
