Oops. Of course, A is the Condorcet loser. I added the second
preferences as an afterthought. I meant
34 A
33 B
33 C
But more examples could be constructed where there is deeper ranking.
Why bother, though?
Condorcet methods, like any deterministic single-ballot method, is a
plurality method, unless voters are coerced into voting for
candidates they do not wish to be responsible for supporting, as with
mandatory full ranking.
