Comments[edit]

SecurePoll and OpaVote disagree on elected candidates. However, since the results from OpaVote were ran, one of the winning candidates have been removed. The .blt file we use to test SecurePoll no longer includes that candidate.

SecurePoll and OpenSTV agree on elected candidates.

SecurePoll and OpenSTV elects candidates candidates 1, 4 and 5.

OpaVote elected candidates 1, 4 and someone they later removed.

Election setup[edit]

  • Candidates: 9 (originally 10)
  • Seats: 3
  • Votes: 29521 (originally 30016)
