This is an odd idea; should parents not be voting for themselves not their children? If they are voting for their children rather than themselves are they not themselves disenfranchised? The fact is that children and their parents have different interests on account of the age gap that is likely to be at least 20 years. Someone who is 16 is much more interested in university fees than someone who is 40 who will be more interested in how much they will have at retirement. Furthermore with turnouts that are often less than 50% a great many children are not being represented by their parents at all. Adults have the choice to not vote, when their parents are choosing not to vote children don’t get this opportunity.
