Some simple ways of dealing with equal rankings in IRV/STV are: (1) "Transferrable Cumulative Vote" - If there are N top-ranked non-eliminated candidates on a ballot, then each candidate receives 1/N of a vote. (This is what I used in my STV-CLE calculator.) (2) "Transferrable Approval Vote" - Each top-ranked non-eliminated candidate on a ballot receives 1 vote. (3) Convert every ballot into a fully-ranked one by breaking ties at random. ---- election-methods mailing list - see http://electorama.com/em for list info
