In mathematical terms, this means that seats are won by parties or groups of like-minded voters in proportion to their support among voters. There are 36 democracies that have at least two million people and a high human rights rating from the organization Freedom House. In the question period, perhaps we can explore which PR systems might be most appropriate for North Carolina. I want to stress that there is no single PR system. Some democracies set a threshold of support required to win office that is much higher than what it theoretically could be.
Some democracies use PR within parliamentary systems.
Others use PR with presidential systems. Some democracies use forms of PR that require voters to vote for only a party. Some democracies eliminate all of the single member districts that we use for most elections in the United States. We of course are not at the point of debating the fine points of PR systems. The more one understands PR, the more one understands how it can have an impact on many of our great political concerns.
