People are different so as their priorities and interests. Stiffler, you may hesitate going around asking for vote as you don't understand why others do that. This implies that your infant/toddler may be losing a chance to win a prize from the competition of that nature. I have already mentioned that those kind of competition is not a fair competition where the merit of a child is judged. So, the best would be staying out of the competition if the parent is confused about vote-campaigning.

Getting straight As, which you consider as the result of kid's work, may not reflect the kid's merit. The role of a parent, who works together with the kid, is pretty much significant. Most (toddler / elementary school) kids, who don't get straight As, fail because of improper environment, mostly due to lack of proper parenting. I believe you understand this. Parent's involvement is necessary for a kid to develop skills and expose merits. The voting campaign is an effort similar to helping a kid by a concerned parent, who is interested keeping his/her kid ahead in a competition.
