Here are the matchups (with their previous two winning percentages in brackets):
(4) Laurier (74.6, 75.8)
(1) King (61.9, 89.5)
It's the mentor versus the pupil. They led the Liberal Party for the first half of the 20th Century and will now go head to head.
(3) Trudeau (50.8, 50.1)
(2) Macdonald (72.5, 92.0)
Macdonald has steamrolled through a pair of modern era Tories in the first two rounds while Trudeau has had to fight and claw for his two wins. This match-up will come down to how effective the right and left are at mobilizing the vote.
