Kathy, Imagine  that  Approval is used to elect the  US President and as in the current campaign the Republicans  are fielding one candidate, McCain.  Does that mean that the big fight for the Democrat nomination between  Clinton and Obama we've just seen would in the Approval scenario be complete

Hi, Kristofer, your idea seems interesting, but I couldn't understand some points: - When you presents simulation results, is the best method the one with greatest or smallest score? IRV is considered the best majoritarian method but its score is between Nauru-Borda and Plurality - In some countr

Tells us little since this is one person's opinion. IRV lets voters state their desires more completely than Plurality and is often better at picking a winner - but sometimes fails badly, so: Not too bad when you do not know of better. I join Kathy in wantng to move to better. DWK On Sun, 22

Yes, this was an excellent (clear basic) example as well. The introduction of new candidates definitely changes the scoring of the candidates by the voters. One can study also voter specific absolute scoring that never changes despite of changes in the candidate list. This is a theoretical

Chris, This is what you are now claiming is a "fairness" condition: ... that to be fair, the winner of an election must not change with the introduction of a new nonwinning candidate, even if the voters change their votes for the prior (old) candidates. As a voter, I would object to this "fairne
