election_title: "Plurality block voting — a 44% minority sweeps all three seats"
scenario_description: |-
  The second electorate in this set (LH-only — see the folder README). Where
  mmp_block_voting.yaml shows a 60% MAJORITY sweeping, this one shows the harder
  version of the same defect: a faction that most voters voted against still
  takes every seat.

  9 voters, 3 seats, 9 candidates. Party Oak (Alma, Bram, Cleo) has 4 voters;
  Party Pine (Dev, Enzo, Finn) has 3; two voters prefer the independents (Gus,
  Hugo, Iris) and spend all three of their marks there. Block voting gives each
  voter as many marks as there are seats, and every bloc votes its own slate, so
  each candidate simply collects their own bloc: Oak 4, Pine 3, independents 2.

  Oak sweeps 3-0 on 4 of 9 voters — 44%. The other 56% of the electorate elects
  nobody, because it is split across two groups and neither one out-polls Oak on
  its own. That is the whole mechanism: block voting rewards the largest bloc,
  not the largest agreement, and the opposition's size is irrelevant unless it
  concentrates.

  This is also ROUND 1 of the two-round method — see mmp_majority_block_runoff.yaml,
  where the same 9 voters reverse this result once the independents are dropped.
  Uncapping the marks reverses it too: mmp_block_approval.yaml.

  Shrunk from the 10,000-voter, 12-candidate table in Wikipedia's "Block voting"
  article. Only the ORDER of the totals carries the lesson, so the electorate
  rescales to the smallest integers that keep every inequality strict.
