I saw some discussion earlier... either in this thread or the political one, that argued about voting being a duty or something similar.
Here in Australia, I think uniquely, for state and federal elections voting is mandatory. It's not something I've ever thought of, really. Once every couple of years (or six times in three years in recent times) we go off to the local school hall, pick up a sausage sandwich, vote, and go home. It's just a thing that we do, as a nation to the point where it's just not even thought about.
I suppose I'm harping on about this cultural divide thing that makes some of the American political stuff so opaque to those of us that don't have to deal with it day to day - but still have to deal with the consequences. So much of what I take for granted here, in terms of both services and cultural norms, are just... so powerfully different to the USA.
