That's almost correct.  "Approval voting" as a term applies to a system
where one can vote YES/NO/ABSTAIN on each of several items.  Condorcet
is one of a series of ranking systems, where one lists items in the
order in which one prefers them.  The problem with all the ranking
systems that I've seen is that there is no way to directly indicate
disapproval.  (This is deadly to IRV, but I don't particularly like that
Condorcet doesn't fix that problem.  The flip side is that ranking
systems generally do well at finding the result that the fewest people
object to even without NO votes.  It is a provable axiom that no voting
system is perfect, BTW.)

That's interesting, but I really am only interested in answers to my
precise question.
