election_title: "Center Squeeze — STV (1 seat = IRV single-winner): same squeeze"
scenario_description: |-
  One of four races in the Center Squeeze election (BV2137, bvid ywckmg; BV-confirmed). 100 voters, three candidates, ONE ranked electorate tabulated four ways. Anderson is the Condorcet winner (beats Reagan 55–45, Carter 65–35) but holds the fewest first-choices (20). Single-seat STV is IRV: Anderson eliminated first, Carter wins. STV → Carter.

  Carter

--- 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 3): Anderson
   Outside (2):        Reagan, Carter
   One member ⇒ Anderson is the Condorcet winner, beating every rival head-to-head.
   RCV-IRV winner Carter is OUTSIDE the Smith set. ✗
      Every member of the set (Anderson) beats Carter head-to-head, yet
      RCV-IRV elected Carter anyway. RCV-IRV is not Smith-efficient (nor
      Condorcet-efficient) — this is the shape a center squeeze leaves behind.
