34% McCain > Gore > Edwards 17% Gore > McCain > Edwards 15% Gore > Edwards > McCain 34% Edwards > Gore > McCain
McCain wins with IRV, even though 66% of voters prefer Gore to both McCain and Edwards. IRV picks the wrong winner. Any election method can exhibit this kind of phenomenon, but with IRV, it's negative impact on social utility is significantly worse.
