I can show (under reasonable strategic assumptions) that my delegated
system SODA elects one of the candidates who beats all with a winning vote
beatpath of length 2 or less, if there is any such candidate. "A beats B
with a winning vote beatpath of length 2" means: there is some C such that
the minimium of (votes for A against C, votes for C against B) is greater
than votes for B against A.
Obviously, if we allow any length of beatpath, and if there are no ties,
there must be some beats-all winner. But is it possible that there is no
winner with beatpaths of length 2 or less? Can anybody give an example of
such an electorate?
