The problem with handling Approval Completed Condorcet in this fashion is
that it creates a strong incentive to truncate those candidates you
disapprove of, even if you have a preference between some of them. In the
example I gave, for instance, it would create a strong incentive for the 12
Gore>Bush>Nader voters to bullet vote for Gore. This denies information to
the preceding Condorcet vote; we may end up with the Approval completion
corrupting the initial search for a Condorcet winner.
As Alex said, it seems that putting a yes/no vote would not be too much
extra effort. A 5 grade (4 grade? 6 grade? ABCDEF?) ballot that allows
implicit yes/no votes by the grade given is a possible solution here, and
allows for very intuitive Approval Completed Condorcet. Has anyone tried
to figure out what criteria are satisfied by such a form of ACC?
If pure ranked ballots are the only option, then I'm still very comfortable
with SSD. It takes a very peculiar circular tie in order to cause any sort
of trouble with SSD.
