Here is a weird piece of trivia: If you follow the link and look at the different "third" parties you will see the American Independent Party and a picture of John G. Schmitz. Schmitz is the father of Mary Kay Latourneau, the kooky schoolteacher that slept with her underage student and had children with him.

It's just that the "third parties" almost never get enough votes to actually make it into the higher offices.
Here's a listing of many of America's political parties with a short description of their basic platform:
