Candidate Clustering

This visualization shows candidates positioned based on second-choice transfers. Candidates whose voters frequently rank each other appear closer together, forming natural "clusters" or voting blocs.

Distance is based on the First Alternate table below — if voters who rank candidate A first often rank candidate B second (and vice versa), they'll appear close together. In STV, proportional representation means winners should be distributed across different clusters, representing diverse voter preferences.

Circle size indicates first-round vote share. Green circles are elected candidates. Hover over candidates to see their top second-choice transfers.

Pairwise Preferences

For every pair of candidates, this table shows the fraction of voters who preferred one to the other. A preference means that either a voter ranks a candidate ahead of the other, or ranks one candidate but does not list the other. Ballots which rank neither candidate are not counted towards the percent counts.

Note: In multi-seat STV elections, pairwise preferences show overall voter sentiment but don't directly determine outcomes, since votes transfer through multiple elimination and surplus rounds.
