Really bugs me how americans talk about “ranked choice voting” because you guys seem to mean STV, which is a form of proportional representation with multi-member districts.
But in Canada, “ranked ballots” meant IRV, which was basically FPTP with a ranked ballot, and ironically exacerbated the worst parts of FPTP like the trend to a two party system.
Stick with the real names of electoral systems!
In the context of electoral systems, “Congress” and “Senate” are multi-seat legislatures. Hence the talk about proportional representation, IE how many Americans vote Democrat vs how many Democrats get elected. Without that discussion you’ll never get a 3rd party elected.
