When I was 10, I kept track of politics, and my political views haven't changed much since then. I certainly had better judgement at 10 than my grandfather the last time he voted a after living with Alzheimer's for a decade. The learning from voting would be worth a little noise around election results where parents or peers convince kids to vote the way they prefer.
