I’m not very well-versed on all this but it seems
Edit: I don’t think this is the best, its just all I’m generally familiar with
First Past The Post
Benefits the two parties in a two-party duopoly system like that of the US. Boom or bust, black or white. When the party in power pisses you off you vote their competitor even if holding your nose.
Seems like there must be a better way, maybe just not as good for those who prefer shooting fish in a barrel
There are versions of PR that mitigate this issue. Mixed-member PR sacrifices a little bit of precision in the proportionality, but limits the seats assigned to party lists to only some additional ones used to balance out the un-proportionality of the results. Most of the elected body is not from party lists.
You can also carry out a vote where you choose the party for the proportional vote, and then rank the members of that party. And the party assigns the seats they win to the candidates with the widest support.
That doesn’t solve the issue of people liking candidates from multiple parties though.
I’ve not heard of that one before, but I can see the reasoning behind it. Is there a name for the system that I can look up?
