We start with the standard system used in the US for presidential elections called "Plurality" , or "First past the post" voting. You can choose only one candidate.

On the surface this system seems fair, it is sometimes described as "one man, one vote" (or today, "one person, one vote"), but mathematical analysis and simulation has shown plurality to have flaws. The biggest flaw, called "vote splitting", happens when there is more than one candidate aligned with your interests.

Because you can only pick one candidate your voting power is diminished by the other similar candidates, called "clones". You are forced to either choose the front runner closest to your interests or vote for your genuine preference and "throw away" your vote by indirectly supporting the other side.

To recap, if you do not vote for one of the two front runners in a plurality election your vote may effectively be against your own interests. By voting for what you believe in you risk indirectly supporting candidates you oppose.

So, go ahead and vote ... pick one candidate below then hit the NEXT button.
