I volunteered at Fairview development center in Costa Mesa CA, which is a place where dozens of disabled residents lived. These people could not talk, move, etc. They were essentially quadriplegics; mentally completely not there; etc. I was a high school student helping move residents to Sunday service and back and doing activities with them (volunteer hours). I clearly remember seeing nurses and others mark ballots of residents that were in no fit state to vote (unable to communicate at all; those who could were often not mentally competent enough to make their own medical decisions, let alone decide who to vote for). I don't think anyone cares to be totally honest. I was shocked the residents even got absentee ballots. Of course, competent adults should be able to vote, but at the point where you're essentially a child mentally? I mean ... how can anyone possibly figure it out. I did lodge a complaint, but nothing came of it.
