This page is an experiment in voting. Half of the people who visit this site vote using Plurality Voting
where a voter selects their top candidate, and the winner is the candidate with the most votes. The other
half use Range Voting where voters score all familiar candidates based on how happy they would be should
that candidate win. You have been randomly selected to vote using Plurality Voting.
