[EM] compromising strategy in Condorcet...

[Markus Schulze]

Dear James Green-Armytage,

compromising is a useful strategy only when there is
no Condorcet winner.

Suppose candidate A is the Condorcet winner according to
d_sincere. Then ranking the candidate B insincerely high
to make him win is a useful strategy only for those voters
who strictly prefer candidate B to candidate A. However,
in so far as d_sincere[A,B] > d_sincere[B,A], candidate A
is still the Condorcet winner when all those who strictly
prefer candidate B to candidate A rank candidate B
insincerely high.
