Successive Rank Voting
-
@SaraWolk Sorry I haven't had time to formulate an answer to your replies, and even this reply will be minimal.
One comment I have is that it IS possible to ensure a majority if all voters express a preference when there is no harm (to more favored candidates) in doing so. The Portland election used plurality voting and allowed write-in candidates, so it was not a true runoff between two candidates. I think RCV/IRV would have produced a majority. In what sense do you mean that IRV does not count every ballot in the runoff?
I would like to know your criticism of the last method I proposed:

It is Bucklin voting for three rounds, and if no candidate has a majority then there is a "true" runoff between the two most approved candidates. By "true" runoff I mean that every voter may express a preference without risk to more favored candidates.
I think your arguments against later-no-harm do not apply if the voter can choose between later-no-harm and no friend betrayal. -
@Jack-Waugh Coombs has some appeal, but I think it has a similar problem to the coercive Bucklin voting that I considered before: voters will not rank their lower choices honestly.

@robertpdx said in Successive Rank Voting:

By "lower choices", do you mean the candidates they absolutely hate the most, or those in the middle? Would you give an example of the voter's rating of the candidates and their dishonest ranking? Are you using my proposed refinement, where a candidate's being unranked by a voter would count against that candidate? A ballot that leaves any candidates unranked would count against every unranked candidate that is still in the running, but not against the last-explicitly-ranked candidate.

@Jack-Waugh I mean that partisan voters will rank their candidate first and the main opposition last. So one (or both?) of the top contenders is likely to be eliminated early.
