A common situation: 2 factions & 1 good compromise.<br><br>The goal: Make sure the compromise wins.<br><br>The problem: One of the 2 factions has a majority.<br><br>A concrete example: true ratings are<br> 55 voters: A 100, C 80, B 0
<br> 45 voters: B 100, C 80, A 0<br><br>THE CHALLENGE: FIND A METHOD THAT WILL ELECT THE COMPROMISE (C)!<br><br>The fine-print: voters are selfish and will vote strategically...<br><br>Good luck & have fun :-)<br><br>
</blockquote></div> <br>Since A has a majority, no method is guaranteed to elect C. If both A and B voters are not sure which faction is larger, it is possible vote for their preferred candidate and C under approval voting, or put C highly rated under range voting, and C be elected.
