I'm curious what impact mandatory voting has on the number of viable political parties. In Brazil, we have mandatory voting and a few more viable political parties (at least at the state and local level). I haven't a clue if there is any relationship, but I would imagine that requiring people to vote would involve having the 63% that isn't voting currently looking at candidates from the two parties and saying to themselves "I hate both, who else is available?"
