Why should children should be allowed to vote at elections? Explain

It would be quite odd to let 10 year olds vote, especially since they know little about politics. However, there is a possibility that teenagers could be allowed. Teenagers have much more knowledge than a 10yo, and they could make good decisions for their age. Children should have a say in our world too, so why not? If they can follow instructions well, their parents could tell them to vote for someone specific, and that would significantly increase the vote count for that runner-up. Personally, I would not want children voting, but you do you.
