I think the Canadian system is very much modelled after the UK?
That’s interesting about Australia though. Btw I understand Australia has a ranked voting system in elections? Curious about how well that works. Our first-past-the-post is a nightmare with vote-splitting sending the “wrong” representative to the capital.
But doesn’t it resolve the vote-splitting problem? For example, a common scenario here is you have a right-wing candidate winning in a a left-leaning district because the left’s vote is split across more than one political party. Wouldn’t a ranked system solve that dilemma once all the dust has settled?
