Take alaska_2022_irv_with_palin.yaml and strike PALIN — a candidate who did not win — out of every ballot. Nothing else changes: no voter is given a preference they did not express, no ballot is reordered, no score is invented. The 23 Palin-only ballots simply have nothing left to say and exhaust. RCV-IRV now elects BEGICH, 93-84 over Peltola — and those are exactly the numbers the full election's own pairwise matrix already reported for Begich-vs-Peltola, because with Palin gone the instant runoff IS that head-to-head. So the loser Palin, not the ballots, decided the 2022 result. That is a failure of Independence of Irrelevant Alternatives on a real federal race, and it is the direct check on FairVote's claim that "RCV is highly resistant to spoilers because it satisfies both the Independence of Irrelevant Alternatives and Independence of Clones criteria". Clone independence is genuinely satisfied here (4 ballots rank Peltola between the two Republicans, so {Palin, Begich} is not a clone set); IIA is not, and IIA is the criterion FairVote's own prose definition describes. Reading it fairly: a real Palin withdrawal would have changed campaigns and turnout too. This is the STRICT criterion test — hold the ballots fixed, remove one candidate — which is what IIA asks and all a certified ballot record can honestly support.

FINAL RESULT Candidate Votes Status ----------- ------- -------- Begich 93 Elected Peltola 84 Rejected Winner(s) — RCV / Instant-Runoff Voting (single winner) Begich --- Smith Set (the generalized Condorcet winner) --- The smallest group whose every member beats every candidate outside it — the honest answer to "who is even in contention?". Smith set (1 of 2): Begich Outside (1): Peltola One member ⇒ Begich is the Condorcet winner, beating every rival head-to-head. RCV-IRV winner Begich is INSIDE the Smith set. ✓ Not guaranteed — RCV-IRV is not Smith-efficient — but it holds here. More: 07_Concepts/topics/smith_set.md
