Rung 1 — two candidates: nothing can split¶

Generated from 07a_apples_two_candidates.yaml — do not edit by hand. Regenerate: python STARVote_LH_tabulation_engine/tools_adam/scripts/build_yaml_pages.py.

Method: plurality · 1 seat · Expected winner: Gala

▶ Live on BetterVoting: vote · results ↗ (election vq78wk · test BV2293).

Scenario¶

Nine people pick ONE fruit for the office basket. Seven of them want an apple; two want a banana. With only two names on the paper there is exactly one way to say "apple", so the apple people all say it.

Gala 7, Banana 2. The apple side holds 78% and wins with 78%.

This is the baseline every later rung is measured against. With two candidates, Choose-One, STAR, Approval, RCV-IRV and Ranked Robin ALL elect Gala, because with two candidates every reasonable method is the same method: majority rule. Vote splitting has not been prevented here — it is not yet possible. It becomes possible the moment a third name appears. Live results: https://bettervoting.com/vq78wk/results
