Considering what "Deep State" could do to undercut Trump--even to the point of preventing him calling in AC130s to destroy the 2020 racial insurrections--two lessons can be gleaned:
1. Biden's incompetence isn't a danger. He's not in charge. So there's no need to impeach him, and thus put Harris in the POTUS position.
2. The Constitution cannot resolve the problem--save for a #Federalist46 State application of 2A.
