Re:Instant runoff voting is the system we need

I kinda see range voting as the solution. To explain my intuition... Technically it's not condorcet, because a pair-wise winner doesn't always win, but if you relax the definition of "pair-wise winner" to allow for each voter to scale down the strength (weight) of their vote, then range voting does in fact always select the candidate which wins all weighted-pairwise competitions. I think whether you buy this intuition has to do with whether you think preference/utility is fundamentally ordinal or cardinal.

Your intuition is in fact correct. Balanski and Laraki have shown that a median based rating system, in the limit where all voters are rational and their utilities are maximized by electing their desired candidate, that the winner is always a Condorcet winner. This is one of the reasons that Majority Judgement (their name for this system) has so much going for it.
