Yes. What I was aiming at was: if IRV were in place, then the C voters would have incentive to betray favorite; anticipating this, candidates like C would see less value in running at all. > > >This incentive (for C to not run, and B voters to not vote for C) is the first > >reason why I find IRV unacceptable. > > There is also an incentive for the C voters to > vote insincerely and rank B first since they may > know their candidate cannot win.

I hear you. I suppose the response is, "Utility is important, and the first rank is the only one that threatens to tell us anything about utility." Myself, I don't see IRV as the solution to this concern, particularly if there's favorite-betrayal incentive!
