I think you should rank A as high as possible but behind at least 1 candidate who you are reasonably sure will be elected. As long as you rank him lower than the expected round that he will be elected in, there is little risk to keeping him ranked high. Also, if he isn't ranked in the first round, then you probably want to give him you vote early. > If looking for links to Woodall and > Hylland, this approach in a way tries to generalize them under one > framework. It probably comes down to deciding what the cost/benefits are of shifting him back 1 rank. A2>A1>.... is just as effective as dropping A1 as long as A1 is elected in the first round. Maybe candidates with strong person votes should advise voters to rank them second. The only time it matters is when they fail to get elected in the first round, and in that case, the assumption of being a certainty of getting elected has failed. Also, some PR-STV methods only look at transferred-in ballots when working out what ballots to transfer-out. E.g. If a candidate gets 0.4: person 0.4: party in the first round, and then gets 0.5 quotas of additional votes in the 2nd round. The 0.4 personal votes (and the 0.4 party votes from the first round) are ignored when working out the transfers as only the 0.5 quotas of transferred-in ballots are considered. ---- Election-Methods mailing list - see http://electorama.com/em for list info
