Document Summary
Plurality method - counts first place votes; the most first place votes wins. Borda count - assigns points based on candidates position on ballots. Instant runoff - if no majority candidate, eliminate candidate(s) with fewest first place votes. Majority candidate - the candidate who receives more than half the total first place votes (51%) If n voters & n is even, majority candidate needs n/2+1 votes. If n voters & n is odd, majority candidate needs n/2 rounded up. First step: 67 total voter, majority is 34, no majority yet. Second step: eliminate candidate c, b only has 33 first place votes, no majority yet. Third step: eliminate candidates a & d, a & d tie for least first place votes. If they didn"t tie, one would win election. Looks at every 1 vs 1 matchup between candidates and sees who wins most matchups.
