Dear Jobst, Draw a ballot at random. Use the ranking on this ballot to rank all of the other ballots from worst to best according to their favorites.
Elect the favorite indicated on the k_th ballot with probability 2*k/(n+n^2) , where n is the number of ballots. Can this be adapted to Range Ballots? My Best, Forest ---- Election-Methods mailing list - see http://electorama.com/em for list info
