Duverger's law explains that we only have two viable parties because we use an antiquated voting system that encourages tactical voting. If you don't vote for one of the top two candidates, you're basically "throwing your vote away."

I would think that IRV (Instant-Runoff Voting) would abolish such foolishness otherwise known as a political duopoly.
