It seems to me that another problem of Copeland methods is that they
encourage favorite betrayal in the same way IRV does: if your compromise
has a better chance of winning the election than your favorite, but your
favorite has a good chance of beating your compromise, then you (and like
minded voters) vote your compromise above your favorite to maximize your
compromise's chance of getting one more win.
