Update: This article describes my initial thoughts on a proportional voting system involving exactly two MPs per riding. I later found out about Dual Member Proportional (DMP) a fully developed system similar in essence to the one described here.
The country of Adanac has recently held its first election using a new voting system called Cooperative Proportional. In this system, every riding elects two MPs who cooperate to serve their constituents’ needs. Since Adanac has 10 ridings, its House of Commons has 20 seats.
