I don’t see it being particularly beneficial or making any difference. With a couple teenagers in my house the discussion has come up more than once about their peers’ behavior.
The saying the “apple doesn’t fall far from the tree” is essentially true.
The kids that are racist assholes are racist assholes because their parents are racist assholes. So they’ll vote the same way. The vast majority don’t care or will vote how tiktok tells them - which is probably how plenty of adults do it - and the kids who come from families that actually give a shit about communities and education will probably vote liberal.
So there might be more voters, but IMO the percentages will remain the same.
