I can see that this definition of "clone" is useful for making
methods satisfy Clone-Winner that otherwise wouldn't. But it
makes Clone-Loser pretty worthless: If some faction is nominating
clones in order to get an advantage, they aren't going to rank
the candidates equal if that isn't advantageous. They'll instead
strictly rank the candidates. But your "clone" definition won't
detect this kind of manipulation.
