The best answer I can think of is the overwhelming inertia from grass roots will be unstoppable - just as it was in Maricopa. Several, including Fann, did not want this but they had no choice. The people demanded it and their careers were toast if they fought against it.

It may not persuade the Pelosi types to give up but underneath all of these corrupt pols is a network of people that will no longer have the stomach to support the obvious fraud. Biden's power, even if he doesn't resign, will be gone. Enough Dems in Congress will read the writing on the wall and not support him because their constituents are giving them an earful if they do.
