It could be taken as the initial method in a sequence of methods in which
my recent method would be the second member, and the third member would
require the voters to (1) rank the candidates, (2) rank the pairs of
candidates, and (3) approve as many pairs of pairs of candidates as
Then the pair of pairs with the greatest approval would be sent to the
ballot rankings of pairs to determine the pair of candidates to be sent to
the ballot rankings of candidates to determine the winner of the election.
Perhaps this sequence could be used for theoretical purposes such as
scaffolding for the construction of a "Small Voting Machine."
