Shouldthe voting age start at 13?

No. I teach middle school and find that the people I know who are 13 generally are not interested in politics. Mainly, they are interested in the opposite sex, how they look, who the "cool" singers/groups are, what the new fashions are, and eating. This is NOT good for voting. We need informed voters ( not that all voters are actually informed, but we can hope.) If you are interested in politics I would suggest you can still become involved in the political process but helping a candidate in his election, and know the issues.
