[EM] Poll on voting-systems, to inform voters in upcoming enactment-elections

[Joshua Boehme]

In an A versus B comparison, since A's "winning votes" are the ones for A, A's "losing votes" would be the ones for B. Eliminating the candidate with the worst pairwise defeat is completely unambiguous, though.


Interestingly this doesn't always resolve a three-way cycle in the typical way (margin matrix is row candidate over column candidate)...

    A  B  C
A  0  2 -4
B -2  0  6
C  4 -6  0

C gets eliminated, leaving A as the winner over B. Most methods would break A's weak win over B and make B the winner.

If B did *worse* against C (B beats C by less than 4), B becomes the winner under this method.
