DMC as generally defined does allow equal rankings.
DMC uses neither margins nor winning votes to measure defeat strength. DMC uses the approval score of the winner to measure defeat strength.
Now it has been suggested to me by Adam Tarr that Conodrcet method that
allow equality rankings and that also use winnig votes not margins,
can avoid the 2-party domination trap. So I suggest to Jobst Heitzig
that he propose a DMC variant that does those things...
what precisely should it be? And then we can ask what happens
to 2-party dominance under (new)DMC.
(If new-DMC actually exists. I have not thought about it.)
