no_condorcet_bv2138 — one electorate, no Condorcet winner, five winners¶
Robert LeGrand's flagship "the method decides everything" example from his ranked-ballot calculator, reproduced on BetterVoting (election cxrf8v, Test ID BV2138). 921 voters rank five candidates with no Condorcet winner (Smith set = Abby, Brad, Dave, Erin); across ~15 methods the win splits five ways.
Read the lesson: bv2138_cxrf8v_no_condorcet.md — the five-way split, the Copeland tie that this repo's engine broke wrongly for two years, and which methods BetterVoting can and can't run.
