In defense of the country (Wow, you might want to bookmark this) there are a number of people who know what they want to do, and it doesn't involve geographical knowledge (eg car mechanic) in a very significant way. They aren't terribly interested in it, either, so they just go on their merry way.
At the same time, there might be some psychology at work here. Since it's so easy to get around to different places in the world, it's no more of a major achievment than owning a big house and a fancy sports car.
Now I know there are a number of people who will throw a hissy fit over them being willfully ignorant, but I'm not convinced it's totally bad. Maybe they're happier that way, and if they aren't participating, they aren't making an impact on decisions either way.
Besides, if more people like that voted, they'd probably vote for Bush. Fear of the unknown is a powerful motivator, which is what Bush has consistently based his platform on. Add in a bit of idealism and you've got a nice blend to convince an uninformed public that you're doing the right thing.
