They still have him out there casting votes, regardless of his ability. Less than a week ago I saw a video where he voted 'incorrectly' and watched as all the aides scrambled to tell him to shut the fuck up and demand that "that one doesn't count" to the room. I've literally seen 4 years olds playing hide and seek with a better sense of awareness, fairness, and object permanence than our incompetent overlords
