While complete ballot data is ideal, I think a convincing case as to how a voting method might perform in a particular election can sometimes be made from polling data. For example, there's good exit polling data for the Senate race in Minnesota that's being recounted, showing that supporters of the Independence party candidate would have preferred Al Franken over Norm Coleman by a 5% margin. That would have given Franken at least another 20,000 votes, way more than the 215 votes he trailed by pre-recount. I think that's a pretty good case that IRV would have selected Franken, regardless of the results of the plurality recount. ---- Election-Methods mailing list - see http://electorama.com/em for list info
