Unfortunately, I have no faith that any democrats in positions of power are turning on Biden. They are trying to protect Joe, while not giving the House any levers to publicize the crimes of the Bidens, and more to the point put a spotlight on the enablers of the Biden’s crimes.
Worst case scenario for the deep state is to get Hunter’s crimes in a court room where the Judge is not Deep state and the jury is not hostile to Republicans. This scenario would allow a judge to compel testimony from Deep staters, with my dream being charging the enablers of Biden under RICO, including Obama (who probably knew exactly what both Hillary and Joe were doing as part of his cabinet).
To see them in such a dilemma would be amusing, but I think the evil geniuses who operate Biden's puppet-strings will come up with a plan to dump both Biden and Harris.
Your worst case scenario for the Deep State--which is an excellent scenario for all honest, benevolent, decent people--presupposes honest government, something that is anathema to the Democrat Party.
