Universal suffrage a good thing?

[Felix_Nietsche]

My brother-in-law is from Brazil and in Brazil you are required to vote. The result is every slobbering-knuckle-dragging-retard votes.

I'd like to see the USA restrict voting by requiring potential voters to take a test. Those who pass get a voter's license good for 12 years. Questions like:
1. What are the three branches of the federal govt?
2. What are the first 10 amendments to the constitution called?
3. What is a veto?
4. How many votes are necessary to override a veto?
5. Which branch is required to submit a budget?
6. Which branch has the power to auhtorize the spending of money?

I think about 25%+ of Americans would fail this test even with coaching. The Democrats would lose most of their voters if such a requirement was inacted so I don't see this happening.
