Voting is Pointless because I have a strong-interest in Democracy

[The Lurker Below]

Why does hardly anyone in the US vote for parties other than the Republicans or the Democrats? Do 98% of the country love either of those two parties that much?

We're taught in school that if we don't have the answer on a multiple guess test to always choose C. Adding more than two options to the election ballot would confuse us too much, we'd all choose C, and the parties would break down into fisticuffs over whose name gets into the C slot.
