That is technically 2 rounds. This would increase the number of voters who end up wasting their vote. Voting for a no-hope candidate first choice would be "throwing your vote away". PR-STV maintains proportionality no matter what order candidates are eliminated (assuming you don't eliminate candidates who have achieved the quota). I don't think this could be used to create a monotonic method though. > Any method of proportional representation must be precinct-summable in > a reasonable fashion The certainly isn't a required condition for it to be a PR method. > The party list system works much better for achieving proportional > representation as long as there is a party representing your > interests.

If each candidate was allowed to submit a list and candidates were allowed to be listed on more than 1 list, then you could have precinct summability while having (a weak form of) PR-STV. Each voter would vote for 1 candidate's list, rather than providing a full ranking and PR-STV could be used to combine all the votes. ---- Election-Methods mailing list - see http://electorama.com/em for list info
