The simplest upgrade from Plurality Voting is Approval Voting. Instead of picking your favorite candidate, you get to pick all the candidates you approve of.
Under Approval Voting, you can approve of your favorite candidate and for any emergency backup candidates to avoid the Lesser of Two Evils dilemma. For example, under Approval Voting, those who voted for both Al Gore and Ralph Nader would have had their votes counted. Likewise, conservative voters for H. Ross Perot could have approved of George H. W. Bush as a backup option.
While simple, Approval Voting doesn't allow you to distinguish between your true favorite and your emergency backup candidates. For that we will look at more complicated systems.
Check the boxes of all the candidates you approve of. Then type the Next button when finished. You need to check at least one before you continue.
