Works for me. People have discussed whether Biden would still be in due to the fact that the electors vote for POTUS and VPOTUS separately, but I just read, I don’t know. I would assume all bills, treaties, hires and appointments would be null and void as well.
obama selected biden as vice-president during his campaign , if congress voids his campaign ( it never happened) then biden was never legally chosen as vice-presiden as obama never had the right to choose a vice-president. biden would go away as well as anything obama did while pretenting to be “president”. You are right it would void all bills,treaties,hires, and appointments.
