A '''Condorcet method''' is any election method conforming to the [[Condorcet winner criterion]]. The method in question must always elects the "beats-all" winner, selecting any candidate who can beat any other candidate in a pairwise runoff. The name ("Condorcet method") comes from the 18th century mathematician and philosopher [[Marquis de Condorcet]], although the method was previously described by [[Ramon Llull]] in the 13th century. Many Condorcet advocates agree that a further criterion that Condorcet methods should pass is the [[Smith criterion]], which means the Condorcet method will always elect someone from the [[Smith set]] when there is no beats-all winner (usually due to the [[Condorcet paradox]]). |
