That's the hope, but as I said, I didn't see a lot of evidence of that. The closest we got to a preference exchange is in Alberta. Most of those cases happened in 1955. There was a scandal about Social Credit, and the CCF, and Liberals suddenly figured out after 30 years, “You know, if we exchange preferences, we can defeat them”, so they defeated four Social Credit candidates through an exchange of preferences. In 1956, Social Credit brought the legislature back and banned preferential voting.
