Revision as of 15:30, 14 June 2005

Please rate the following single-winner methods on a scale from 0 to 10, on functional merit alone. That is, leaving the issue of public salability aside, how well will the method perform in a large, contentious electorate? Decimal ratings are allowed.

The answers you give on your first pass through the survey need not be final. Please feel free to change/update your answers as many times as you like.

Feel free to add more methods to the poll, especially interesting ones! This goes without saying, but please don't change other people's ratings! The format of this poll is based on that of the essential questions poll. Please identify yourself by your initials in the body of the poll, and in the participants section at the top of the poll.
