I honestly don't know, Susan. My intuitive sense is the Democrats will have to do things that aren't in their collective DNA, and that's get in the mud with these people. The first question that the Democrats should ask themselves every day is, "What's is the most efficient way to draw blood from the GOP?" And by efficient, I mean, "What sort of demagoguery can I do that will shift public opinion away from the GOP?" It's not enough to punch them repeatedly in the face as hard as you can. Any attack has to be calibrated to both maximize the amount of pain inflicted to the GOP while shifting public opinion towards the Democrats. So when a toddler dies of measles due to anti-vax propaganda, the Democrats should repeatedly and without mercy blame RFK Jr.. When AIDS-related deaths skyrocket in Africa, the Democrats should repeatedly and without mercy attack the "Christians" in the government who made it happen.
The key thing to remember is, there are no rules. The GOP has chosen this path, so that's where we have to engage them. When the GOP plays the victim, the response needs to be, "fuck you" followed by a punch in the face. When the media cries "foul", the response needs to be, "fuck you, you're complicit with the failure of our system of government."
Every movement has a pressure point, and the GOP for all their big dick swagger are thin skinned. Find their pressure point, and hit it hard.
