Scenario¶

Race 2 of 2 in the Coombs No-Show pair, part 2 of 2 (BV2166, bvid b7b8dv; BV-confirmed). Source: Dan S. Felsenthal (2010), Appendix A7, Example 19 (continued) — see bv2166_b7b8dv_star.yaml for the setup. The 13 remaining voters under Choose-One: first choices Amy 4, Boone 4, Cass 5 → Cass, exactly as with all 15 (BV2165). The first-choice count never wavers; the no-show flips live in Coombs' elimination (on paper) and STAR's runoff (live). Live results: https://bettervoting.com/b7b8dv/results
