Teenagers and children are not mature enough to vote independently of their parents. Neither are adults, by that logic. In addition, let me add that I support the complete abolition of any voting age restriction because the age of maturity is reached at different ages by different people. Children at the age of eleven are allowed to testify in court and the jurors are generally instructed to treat the testimony of a child the same as the testimony as an adult. Teenagers are more easily swayed by advertisements than adults are.
Children also seem to be better at recognizing lies than adults.
Also, adults with busy lifestyles don t spend the time to research politics. Teenagers are often more informed about society because they have time to think about a subject before finalizing an opinion on it. This extra time also translates into more interest in voting. Teenagers do not have enough real world experience to vote responsibly. Although that person is rather unlikely to vote, it would be considered extremely unconstitutional to take away that right.
