No proxy. Pelosi let the house proxy during COVID but iirc senate never did.
“Brain dead” is probably clinically an exaggeration unless more strokes happened. Hiding this to avoid an election will be difficult and must be exposed.

Won’t make any difference. Dems will just cheat. Voting in this country is done, probably forever.
