I've seen how adults vote and honestly I don't think there's a measurable improvement as people age.
Additionally, it's unfair to say "X shouldn't vote because I don't like how they'd vote" — my argument that if you're employed there are a lot of laws involved in how/what/when you're employed. If we trust someone to work a somewhat dangerous or strenuous job, then we should trust them to vote.
It's hypocritical to say that a minor can operate heavy machinery or handle dangerous materials, but they're not mature enough to vote for elected representatives.
