Expanding the electorate to include children with brains still undeveloped is a bad move. There is plenty of evidence that teenagers, including those who already can vote, have trouble grasping complex issues. Yes, that happens in other age groups too, but not at such rates.

Think of all the dumb, stupid things you did when you were 16 and about all the things your friends did. That's the kind of people that are given the vote. How can that improve the state of democracy? How can that lead to better policy? When you increase the number of voters by the most impressionable and unstable section of the population?
