You can combine all of those methods (though not IRV) into a super-ballot. I think this was suggested on this list at some point. Basically, you give each candidate a rating, but fractional rankings are allowed. You then construct the condorcet matrix. If a voter ranks A as 1 and B as 1.5, then that counts as half a vote for A over B. However, if the voter votes A as 1 and B as 5, then that only counts as 1 vote for A over B, since each voter gets a maximum of 1 vote. Ranked candidates are considered preferred by a full vote over unranked. This allows the voters to decide which method to use. Condorcet - just rank the candidates in order of your choice, equals allowed Approval - rank approved candidates as 1 Range/Scorevoting - rank all candidates from 0 to 1 (0 = favorite) Each voter could decide, without one group having much more power than others. Abstains aren't handled that well. Scorevoting assumes that they should have no effect. In theory, the rule could be that if a candidate is not ranked, then no preference ordering is assumed. The ballot would have a zero for all comparisons relative to that candidate. However, that is a lot of hassle, maybe there could be a box to indicate how you want unranked candidates handled. Do you want them equal lowest rank, or abstain. ---- Election-Methods mailing list - see http://electorama.com/em for list info
