It's true that we we don't discuss most voting systems here--only the ones that we really like. (But we discuss IRV and Borda a little, just because they're fairly frequently proposed or mentioned in popular articles). Nanson meets Condorcet's Criterion, but it fails all the defensive strat

[EM] Approval and ICC

2005-06-13 Thread MIKE OSSIPOFF
Approval has no such problem because the Bush supporters can simply vote for both Bush-A and Bush-B. If they tie, a coin is flipped and one is elected. Since they are exact clones, either one will do. Clones aren't necessarily identical. People who prefer the clone set to all others can hav

I'm going to indent this so that it will be clearer. But, because experience has shown that e-mail can scramble indentations, I'm going to number and letter the subject headings too: This, like most of what I say about ranking strategy, is about the acceptable/unacceptable situation. It's

[EM] IRV _does_ meet IICC

2005-06-13 Thread MIKE OSSIPOFF
In a rather careless error, I said yesterday that IRV fails IICC, the weaker relative of ICC that involves an indifferent set instead of a clone set. Actually IRV passes that, just as it passes ICC. IICC is easier to pass, and I don't know of anything that passes ICC without passing IICC. I ha

Mr. Gazeley, Thank you for writing to the list. I remember your article with I.D. Hill about sequential STV. Are you aware of Nic Tideman's CPO-STV? Anyway, back to your topic. Many of us are aware of Nanson's method, but it is true that we do not discuss it very often. My

Title: NANSON - Elections to one seat I was disappointed to see no reference to Nanson on this site. Nanson proved in effect that if a series of Borda counts is conducted on the same set of votes, eliminating each time the candidates whose scores are equal to or below the mean, the one can
