election_title: "Block voting — the smallest possible minority sweep (5 voters)"
scenario_description: |-
  The floor case: the fewest ballots in which a minority can win every seat under
  block voting. Five voters, three seats.

  Two voters mark the full slate — Nora, Omar, Priya. The other three each mark
  one name, and a different one: Quinn, Rosa, Theo. Every slate candidate finishes
  on 2, every lone candidate on 1, and the slate takes all three seats on 40% of
  the voters.

  Five is the minimum. With four voters the slate bloc would need 2 of 4 to
  out-poll each rival, which is half the electorate, not a minority; three
  dissenters voting three different ways is the smallest opposition that is both
  larger than the slate and unable to beat it anywhere.

  Two things this case is NOT. It is not an argument that block voting usually
  does this — it shows the shape of the failure at its smallest, the way a
  two-candidate example shows vote splitting. And it is not about bullet voting
  being a mistake: the three dissenters have no better move available. Each has
  three marks and one candidate they like; spending the spare marks on someone
  they don't want is how a voter defeats themselves. The corner they are in is
  the method's, not theirs.

  The full-size version of the same mechanism, with two organised parties and a
  runoff: mmp_minority_sweep.yaml.
