[[File:2D election example with vote splitting and spoiler effect.png]]
This is an example simulation of an election on a 2-dimensional [[political spectrum]] (such as the [https://www.politicalcompass.org/ Political Compass], [https://www.nolanchart.com/survey-php Nolan chart], [[W:Pournelle chart|Pournelle chart]], etc.; it doesn't matter what the actual axes are.)
There are 3000 voters (blue dots), 3 candidates (red dots), and voters vote honestly, supporting the candidates who are most similar to them ideologically (nearest distance).
*C is a partisan candidate on the right
** C wins under [[First Past the Post electoral system|first-past-the-post voting]], since A and B split the votes of the left wing of the electorate.
*A is another partisan candidate, this time on the left
** A wins under [[Instant-runoff voting|Instant-Runoff Voting]] ("Ranked-Choice Voting"), after B is eliminated for not having enough first-preference votes, leaving A and C.
*B is a moderate candidate, and the best representative of the average voter
** B wins under [[Score Voting]] (with normalized ballots), as they are the highest-rated overall by the voters.
