Coming up on Fox News Network:  should people with Dementia keep the right to vote?

IMHO, only if they are Democrats.

As long as people with Dementia can run for office, those with Dementia should be allowed to vote.

no

Communist Goal #32. Support any socialist movement to give centralized control over any part of the culture--education, social agencies, welfare programs, mental health clinics, etc.

Communist Goal #38. Transfer some of the powers of arrest from the police to social agencies. Treat all behavioral problems as psychiatric disorders which no one but psychiatrists can understand [or treat].

Quoted: If someone has a court-ordered guardian, then they should not vote.  This is a law, I believe in nearly half of the United States. It's the standard of judgement that would be my only concern.

That makes perfect sense.
With possibly rare exceptions anyone who cannot go into the booth and vote themselves should not be allowed.

What is going on this election has gotten ridiculous. If you want to vote you should be at the place appointed on the proper day. End of discussion. If you are too stupid to figure that out you shouldn't be voting anyhow. Obviously, people who are not in the US should use absentee ballots but what is going on in this election is going to cause nothing but problems down the line.
