5 ABCD 4 BDAC 3 CDAB 1 DBCA ... P.S. The minimum total distance criterion would give the win to A in the above example. IRV also picks A. Who would win under the rules of Ranked Pairs? Forest -- all preferences are expressed so all criteria give the same result: A (8) > B (5), A (9) > C

Hi Forest. I find your message incomprehensible and most of the problem is with the English words. This is not a message that is sent merely to create an opportunity for you to subsequently write nothing. The geometry of voting is somewhat really simple. There is plain space and a dimension for

The geometry is not obviously Euclidean since there might not ever be a formula that calculates the Euclidean distance (the square root of the sum of the squares of differences in the weights, over all kinds of papers). Also rules that use normalised weights seem to be less likely. Suppose there

Here's the version of Candidate Space (CS) that I like the best now: The ballots must have some way of determining favorite, so must have at least the expressivity of Majority Choice ballots. [The favorite on the expressive side of the ballot must have maximal positive instrumentality in the inst

I took it for granted that "favorite" would also be among the approved on Majority Choice ballots, and that favorites would be determined from the rankings or ratings in the case of CR or ranked ballots. But I still think that CS as I proposed it suffers from a fault. If the race is perceived as
