Not MMPR, but biproportional rep

[edit]

@Erinthecute @Iamthinking2202 (Since you two wrote the article): I believe this is just the German term for biproportional representation, rather than being a kind of MMPR. MMPR has Mixed (i.e. both party-list and individual constituency) membership; biproportional representation involves only a single kind of member, where proportionality is achieved by electing runners-up from underrepresented parties. It may need a partial merge (i.e. move most of the info to the biproportional rep article, while keeping specific details relating to its use in Baden-Wurtemberg here).–Maximum Limelihood Estimator 03:54, 3 May 2024 (UTC)[reply]

Hey @Closed Limelike Curves,
I think I do see where you’re coming from, but I’m not sure if partial merger is needed. From what I’m getting, the biproportional representation article (a bit hard to parse) relates more to
getting a national amount of seats, and then dividing that into seats per region (which themselves have different vote shares), akin to how the list seats are allocated by German states, after coming up with a national total.
As far as I see it, this is like MMP but entirely made up of best losers, vs MMP with party lists - that also allows best losers (eg Annalena Baerbock in 2021). iamthinking2202 (please ping on reply if you would be so kind) 00:34, 4 May 2024 (UTC)[reply]
@Iamthinking2202 Hmm, I think you might be right. From what I can tell, biproportional apportionment can be done either with open or closed lists; I was a bit confused by the redirect from Fair majority voting, which uses open lists. In that case, Zweitmandat seems like a combination of biproportional apportionment with open list? –Maximum Limelihood Estimator 02:56, 4 May 2024 (UTC)[reply]
@Closed Limelike Curves I suppose biproportional representation with open lists is a way to describe it, but when you put it like that now I’m not so sure.
With open list systems, you can specifically choose someone on the party list, whereas with this system you don’t get to choose directly - it’s just best losers - and you have one vote.

Yep, so it's the mixed single vote variant of open lists. –Sincerely, A Lime 06:16, 9 May 2024 (UTC)[reply]
@Iamthinking2202 I think I've worked it out: is this the same as dual-member proportional representation, and a variant on localized lists? Ideally I'd like to consolidate more information on this system into a single article, since the localized list article is quite sparse and unsourced right now. —Closed Limelike Curves (talk) 17:15, 17 August 2024 (UTC)[reply]
