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.
