Do you think there should be prerequisites for ones ability to vote?

It seems there are a lot of ignorant people voting, people who don’t understand issues thoroughly enough to have an accurate opinion.

I was watching starship troopers, and it has spawned a few questions I’ve asked on here. But in the movie, in order for people to vote, youneed to first be a citizen, and to be a citizen, you need to serve your government in some way. Not to say that’s such a good idea, since people who serve often will have much different opinions than people who don’t when it comes to voting on issues.

What kind of prerequisites to voting do you think would be nice to have in place? Or do you think everyone should have the right to vote regardless?
