This is part of the problem. When you send the message that you expect them to do nothing, they will absolutely do nothing, and that's YOUR fault for surrendering in advance.
We have to let them know that we EXPECT them to act decisively, and them punish them on Election Day if they won't do what they are told. The Reagan Republicans did that, and took over their party from the old guard, and it led to them having far more power than they should.
The Dems have to reproduce that success, and they will have the advantage of Trump's death in the not so distant future. When that happens, the Trump Cult of Personality will fracture, the knives will come out, and the back-stab ing will begin. The Dems should have a plan in place to capitalize on that chaos among MAGA.
