I had written:

you asked:
>Do you mean sincere "Condorcet winner"? 

	No, not really. I mean it sort of like as if sincere votes are cast, the
outcome is reported, and then is there a CW or isn't there?; and is there
a group of voters who could get a mutually preferable result using the
compromising strategy, or not?
	Because, there could be a sincere Condorcet winner, but some other folks
might use a burying strategy or something, creating a fake cycle, in which
case compromising incentive is likely to appear. So that's not what I'm
talking about. I meant kind of like "no Condorcet winner in an
intermediate outcome", or something like that. Does that make sense?

>And by "Condorcet's method" do you specifically mean

	Nope. WV or margins; minimax, beatpath, ranked pairs, river... I assume
that the same proof would apply to all of them... but if there is a proof
that just applies to some of them, that's okay I guess.
my best,
