--if "Dodgson" minimizes the total travel distance for all candidates
on all ballots to "travel" from their current position to the
output-permutation's position,
and "position" means "rank" then all you need to know is the total
number of times candidate X is in rank Y on any input ballot, for all
(X,Y).
That count-info is publishable by each precinct. For N candidates this
is N^2 different counts published by each precinct.
Right?
