[Election-Methods] Borda-elimination, a Condorcet method for public elections?

2007-12-20 Thread Ian Fellows
Hi all, I've been thinking a bit lately about the lack of Condorcet methods in public elections. I have written a rough outline of why Borda-elimination (Baldwin) is an attractive option for implementation in the public sphere. If you are interested, check out: http://thefell.googlepages.com/

"Condorcet" caught my eye - I think it deserves more attention but do not know how to get there. I see Borda as more complex, without offering benefits to justify the cost. I do not see counting Borda as a flavor of Condorcet. Answering your questions: 1- Condorcet is understandable if p

Dear Ian Fellows, the Nanson method and the Baldwin method violate monotonicity and independence of clones. They also violate the desideratum that candidates, who are not in the Smith set, should not have any impact on the result of the elections. When you try to get a Condorcet method adopted so

Conceded that some could like IRV, even after understanding what it does. HOWEVER, what it does is hidden behind its advertising, and its popularity should plummet like a rock if a true description was seen by more. The description does not have to say "failure", as I see appropriate - jus
