Absolutely not. Even at 18, people are not mature enough to handle the responsibility. I remember when I was 18 and listened to my classmates and their reasons for voting for whom they voted for. Even at that age, I could recognize dumb reasons for the decisions made. I remember some of the children (at 18) thought it was a good idea to have a "peanut farmer" as president. Even more liked the southern accent. That is the mentality of 18 year olds. BTW, it was 1976, Jimmy Carter was elected. Gee, he was great for the economy.
