To paraphrase George Cabot, democracy is governance by the worst. In the abstract, it's easy to view that as an elitist position, but when democracy threatens to give a hateful narcissistic fool the leadership of one's society, perhaps Cabot's take is a little more understandable.

A proposition (that is very unlikely to be taken seriously): the right to vote should be earned, not simply granted. How? By demonstrating awareness. Prior to each national election, every citizen who wants to vote should have to pass a test covering fundamental history and current events. If you can't name your senators, or identify your state capital, you don't get to vote. If you can't find Iran on a map, or name one of the presidents who sat during the Vietnam era, you don't get to vote. Thus, voting would be limited to those who take a real interest in the world. Those who don't can contribute best by watching from the sidelines.
