Ooh, that's an interesting one. Thanks! I've used a system before (no idea what it's called) that gives each voter a number of points (say 10) that they can distribute among the candidates. They can give all 10 points to one person, or spread them out. Of course, your average voter would find this way too confusing.
From the Wikipedia article:
> FairVote [argues Approval Voting] can result in the defeat of a candidate who would win an absolute majority in a plurality system, can allow a candidate to win who might not win any support in a plurality elections
This sounds like a good thing. You end up with an elected official that satisfies most of the population.
51% of voters think Alice would be the best person to lead, they'd be OK with Bob but think Carol and Dan are morons. 49% think Carol would be the best person to lead, they'd be OK with Bob but think both Alice and Dan are morons.
So now if we use normal majority voting, Alice wins and 49% of voters have an elected official they think is a moron.
With Approval Voting, Bob will win. Sure, he might have been everyone's second choice, but he's EVERYONE's second choice. So now we're all reasonably happy.
There is a skeptoid episode[0] from 2011 that overviews the different types and some of the science behind it. And, it even mentions the difference between a voting system and a ranking system.
