A real-everyday living example of IRV manufacturing a final result which differs from what might be anticipated under a first-previous-the-article or the two-spherical voting process is the result to the seat of Prahran while in the 2014 Victorian point out election. On this occasion, it had been the prospect who at first completed third (Greens applicant Sam Hibbins) in the key vote went on to win the seat over the back again of favourable Choices from the other two small parties and independents, narrowly beating the next-rated applicant (Labor prospect Neil Pharaoh) by 31 votes, and the 1st-rated prospect (Liberal applicant Clem Newton-Brown) by 277 votes.
IRV is just not a proportional voting strategy. Like all winner-just take-all voting approaches, IRV tends to exaggerate the volume of seats won by the most important events; small events without majority help in any given constituency are not likely to make seats in a legislature, although their supporters will probably be additional likely to be part of the final choice involving the two strongest candidates.
