They aren't mature, at least not a majority of them. Since we can't use a test to determine maturity, I guess the mature ones will have to wait until the rest catch up or at least get older. Don't forget the soreheads whose candidate didn't get nominated so behaved in an immature way by not voting at all or voting for the opposite party in anger. They should be encouraged to work for what they believe meanwhile and "man" the phones and flyers, etc. They have active ways to make their voices heard until they qualify at 18.
