Yeah, but they don't exist at the moment (no candidates and the people running it lost interest).

There's literally dozens of parties, but only four serious contenders. For most parties that are registered, only the founder runs for office and promptly loses. Then they realize that they're better off just writing letters.
I would've voted for the Rhinoceros Party, though. According to what I've heard, they got really close to actually having an MP elected to the House in the '70s.
