Scenario¶

Race 2 of 2 in the Borda-SCC election (BV2161, bvid q3h4fk; BV-confirmed). Source: Dan S. Felsenthal (2010), Appendix A5, Example 15 — see bv2161_q3h4fk_star.yaml for the setup and the profile note (the paper's printed C>A>B bloc is arithmetic-corrected to C>B>A). The same 7 voters under Choose-One: first choices A 2, B 2, C 3 → C. All three live counts (STAR, Plurality) and Borda's paper count pick C; the paradox on the case page is Borda's SCC instability — B's exit flips Borda (and, honestly, any two-candidate count, since A beats C 4–3) to A.
