People who have lived through abusers recognize this pattern. "It's my fault. If only I had placated him somehow." It's not that X is just rotting Dem elected/staffer brains on propaganda, it's also doing abuse conditioning to get Dem leaders to blame themselves for MAGA's depredations.
I think we've jumped straight to stage 4. 1. I can change them, I know I can. 2. I'll wait till they're sober, then they'll see sense. 3. If I keep my head down, maybe they won't punch me in the face. 4. One of us is going to end up dead.
It's about getting Dem leaders to blame "the left" and "the groups" and fear the right. The only way they'll blame themselves is "I screwed up and listened to the left and the groups. Only billionaire donors and James Carville from now on!"
