Those school elections are of course mock elections just to get young kids to express more interest in politics (a very important skill that sadly more than half the country lacks). I remember the mock election I had waaay back in 2000 where I, an 8 year old kid, voted for Bush. You may laugh at this, but what could you attribute reasons in an 8 year old? I voted for Bush because his opponent was Al
Gore, a frightening last name for a little kid
So moral of the story, don't take any votes your child writes in a mock election seriously, they don't yet have enough mental fortitude (hell, not even some adults do) to cast a reasoned vote.
