I guess I'm trying to nail down the point that whatever constitutes the basic "threshold" for voting is also a political argument that would face almost (if not the same) issues within an preparatory system than without. In fact, at least in the U.S. where I am, one of the purposes of primary schooling is to do just that, i.e., provide basic knowledge of what is involved in required a U.S. Civics course. So, where does that line get drawn? Who decides, and how? The current regime? The line seems to have always been in motion. I don't think there's an institutional answer to it.
