These four are not a complete list. I should compile a list of countries that follow the constitutional principles I am pointing to here (which, as alexgieg points out, is not neccessarily the same as “The Truly Free World”; I hope to better define The Truly Free World in follow-ups to this post), but I can list Finland, Sweden, Norway, and Iceland as also fitting this description off the top of my head. I would not be inclined to list Australia, which uses IRV, though why I have that intuition, and whether that intuition is correct, is a subject for a later conversation.
