User:MarkusSchulze/Wikimedia Board of Trustees elections, 2009

In July/August 2009, Wikimedia used the Schulze method for the election to its Board of Trustees: Three vacant seats had to be filled. There were 18 candidates.

Stage 1
Each ballot contains a list of all candidates. Each voter ranks these candidates in order of preference. Each voter gives a '1' to his favorite candidate, a '2' to his second favorite candidate, a '3' to his third favorite candidate, etc..

Each voter may ...


 * ... give the same preference to more than one candidate. This indicates that this voter is indifferent between these candidates.


 * ... skip preferences. However, skipping preferences has no impact on the result of the elections, since only the order, in which the candidates are ranked, matters and not the absolute numbers of the preferences.


 * ... keep candidates unranked. When a voter doesn't rank all candidates, then this is interpreted as if this voter (1) strictly prefers all ranked to all unranked candidates and (2) is indifferent between all unranked candidates.

Stage 2
In total, 2940 valid ballots were cast. Each figure represents the number of voters who ranked the candidate at the left better than the candidate at the top. A figure in green represents a victory in that pairwise comparison by the candidate at the left. A figure in red represents a defeat in that pairwise comparison by the candidate at the left.

Stage 3
As there was no circular tie, the Schulze ranking was identical to the direct comparisons of the candidates.

Therefore, the Schulze ranking was:


 * Ting Chen
 * Kat Walsh
 * Samuel Klein
 * Gerard Meijssen
 * Domas Mituzas
 * Thomas Braun
 * Jussi-Ville Heiskanen
 * Steve Smith
 * Dan Rosenthal
 * José Gustavo Góngora
 * Brady Brim-DeForest
 * Lourie Pieterse
 * Adam Koenigsberg
 * Ralph Potdevin
 * Beauford Anton Stenberg
 * Gregory Kohs
 * Kevin Riley O'Keeffe
 * Relly Komaruzaman

As three vacant seats had to be filled, the winners were Ting Chen, Kat Walsh, and Samuel Klein.
