I think, in the end, this is probably the best plan. The "spares" give an added bonus that voters get more choice. Under Meek, would this just be a matter of setting the resigning candidate's keep value to zero? Setting a candidate's keep value to zero should only increase the vote totals of all the other candidates. Thus, all elected candidates would stay elected and Meek's method never changes the keep values to eliminate an elected candidate. The problem would be that setting an eliminated candidate's keep value back to 1 could bring an elected candidate below the quota. One option would be to set all "running" candidates at the highest possible keep value such that all elected candidates have more than a quota worth of votes. ---- Election-Methods mailing list - see http://electorama.com/em for list info
