election_title: "Favorite betrayal (RCV-IRV) — BETRAY: 2 Left voters rank their favorite SECOND, and win"

scenario_description: |-
  The honest election (fb_irv_honest) exactly, with ONE change: just 2 of the 12 Left
  voters betray their favorite — they rank Center FIRST and Left second (Center > Left >
  Right) to keep the compromise Center from being squeezed out. Now Left has the fewest
  first-choices (10) and is eliminated instead of Center; Left's ballots flow to Center,
  and CENTER wins the final 21-13. By ranking their true favorite second, those 2 voters
  got a far better outcome (their second choice instead of their worst). That is
  "favorite betrayal": under RCV-IRV, honesty is not always safe — putting your favorite
  first is only safe when they're either very strong or have no chance at all. STAR and
  Ranked Robin remove the incentive: see fb_star_honest, where the HONEST ballots already
  elect Center. Concept: favorite_betrayal_voting_301.md.

video_script: |-
  Same 34 voters — we only moved 2 Left voters to rank Center first instead of Left.
  That's the betrayal. Now Left is the one with the fewest first-choices, Left is cut,
  and those ballots lift Center to a 21-13 win. Two strategic voters flipped the result
  from their worst choice to their compromise. A voting method shouldn't reward you for
  hiding who you really like — STAR and Ranked Robin don't.
