Canada is slightly different though because of its sheer size, there is a concern that proportional representation could drown out the interests of some groups. For example, right now, without proportional representation, politicians still have to take the time to campaign in rural and Northern areas, because these people’s votes matter. With proportional representation though, there would be no need for this though, because these people would make up such a small fraction of the total vote. With proportional representation a politician could neglect anyone living more than a 2 hour drive from the US border and it would make barely any difference to how they do on election night.
I’m not saying this because I’m trying to argue against proportional representation, I just don’t know if this is a fair comparison.
