The keystones of his campaign are Medicare for all, money out of politics, and get out of the war with Iran and concentrate on things that benefit USians. All these positions are favored by a considerable majority of USians.

He doesn't get to pick the keystones. The voters do. He hurt himself badly with wide swatches of the black community by supporting Uncommitted, particularly against Harris - who had enormous support in that community. He hurt himself deeply with wide swatches of the jewish community with his positions on Israel and his decision to make that such a big keystone in his primary campaign, which limits his ability to pivot away from it here in the general.

Who will be the target of the regime's pogrom next year? Hispanics, again? Or Muslims?

Perhaps all of the above, and including black people to boot. But that's a reason why the "blue dots" aren't going to make a switch the way you are suggesting. Those districts are nearly all majority-minority, and nearly all those elected Democrats are themselves minorities. They're not switching to white nationalism, and they're not going to be declared "untouchables" by the national party as I think you were suggesting above. But again, I still think I'm misunderstanding what you're saying...
