That's why we want an election method that can find the compromise choice that serves 60% of the people when we might otherwise get some faction's 40% or 41% choice. Of course, majoritarian methods like Condorcet can't guarantee 60%, or anything over 50.1%. But anyway, I agree

hi James, thanks for the reply. comments below. ER-IRV(whole) is more of an IRV-approval hybrid, and does a better job of reducing the incentive for the compromising-reversal strategy, but ER-IRV(fractional) is probably more acceptable to the general public, and less likely to anger

Hi James, and welcome to the list. I am convinced of the technical superiority of Condorcet over other methods. I agree with you there. But keep in mind that Condorcet is not a single voting method but rather refers to any Condorcet-efficient voting method, the variety of which is
