agree with this entirely. Yes it's true that most eleven year-olds probably aren't knowledgeable enough to make a well-informed choice about political candidates, but the evidence overwhelmingly indicates that most fifty year-olds aren't very well-informed either. And yet, everyone gets to vote (and, of course, many people choose not to). Everyone, that is, except for that would-be eleven year-old voter.
