In my post on electoral reform and the preferential ballot, I remarked that changing the rules benefits some players more than others. This is true of any change, and I suspect it’s one reason why electoral reform has been so difficult: the sense that the rules are being tweaked for someone else’s benefit.
As the centrist party, the Liberals would probably benefit from ranked or preferential ballots (and modelling appears to bear that out), and, funnily enough, ranked or preferential ballots happen to be Prime Minister Trudeau’s preferred option. So it’s easy to complain that the Liberals are rigging the game in their own favour.
But it’s important to keep in mind that, despite the lofty rhetoric about a “fairer” electoral system in which “every vote counts,” proportional representation also benefits some players more than others. The question is, which players?
