Each possible complete ranking of the candidates is given a "distance"
score. For each pair of candidates, find the number of ballots that
order them the the opposite way as the given ranking. The distance is
the sum across all such pairs. The ranking with the least distance wins.
 
==Strategic Vulnerability==
Kemeny-Young is vulnerable to [[Tactical voting|compromising]], [[Tactical voting|burying]], and [[Strategic nomination|crowding]]. It fails [[cloneproofness]] because adding a clone can cause a non-clone to be elected, and this effect increases as the number of clones increases.
