I believe that (except for the margins vs. wv controversy) most
Condorcet fans agree on how to pick the winner in a three way single
winner race: if there is no CW, break the cycle at the weakest link.
Now suppose there is a candidate X who wins by this standard in every
three-candidate subset of the form {X,Y,Z}, where Y and Z are from
among the other candidates in the race. In other words, X either beats
both Y and Z, or there is a cycle in which X's defeat is minimal. Then
we could say that X is a kind of generalized CW, or GCW.
GCW Criterion: If a method M always chooses the GCW when there is one,
then the method M satisfies the GCW criterion.
Comments? Has this been discussed before?
