election_title: "Exercise 2 — The tenth ballot: all ten ballots"

scenario_description: |-
  The same nine ballots plus the forgotten tenth — a voter whose favorite is
  Alex (5), with Chris at 2 and everyone else at 0. The ballot ADDS more to
  Alex's total than to anyone else's, yet it flips the win away from Alex:
  scoring round Alex 32, Chris 26, Bella 25, Eli 22, Dana 20 — the extra 2
  points lift Chris past Bella into the runoff, and Chris beats Alex
  head-to-head 6-4. STAR fails the PARTICIPATION criterion: casting an honest
  ballot can occasionally hurt your favorite (here, by changing WHO Alex has
  to face). Part of the exercise ex02_tenth_ballot.md. Ballots adapted from a
  RangeVoting.org example, posed as an exercise in Brendan W. Sullivan,
  "An Introduction to the Math of Voting Methods" (2022), ch. 5.
