I listen to the CBC daily, today’s Ottawa Morning has FairVote on and it’s been a good segment.
The guest (missed his name) is doing a great job explaining the issue and how proportional representation works.
The clips I think can be relistened to on the CBC Radio app or their podcasts, but I’m not sure how to find them
Here’s a direct link to the segment you mentioned …
