Thanks very much. Let me clarify my question... Which approach is right? The only non-PR way I can think to do IRV to obtain a ranking of the candidates is to 1. find the IRV winner 2. delete him from all the ballots as though he hadn't been an option 3. repeat. This seems like too

Thank you very much! That is exactly the answer I was looking for, and confimed my experience with playing around with it. Ah, I get it. This isn't like IRV so much as Bucklin. That is definitely an easier way to go. With IRV, in the above scenario, only the votes for second of the 9 C
