Multimember systems have been used in the US, on a local scale. The
lack of such systems in the current day might just as well be due to
that there is no modern day League of Proportional Representation
such as the one whose efforts helped get STV into New York, than
that multimember systems themselves are too complex.


Fair enough. But note also that this was just the lesser of my two 
stated hurdles to MMP. 


STV is not mixed member proportional. As for the complexity issue, STV 
seems to work where it has been implemented. I agree that complexity 
will put a bound on how large each district can be, but as long as you 
keep below that size, it should work.


If you have a district size of 5 members and 10 parties, that would give 
a seemingly unmanagable number of 50 candidates. However, voters can 
chunk by considering these candidates in party order. First they can 
consider do I like party A more than party B, then which of A's 
members do I prefer?. They do not have to rank all 50 members either, 
and few would.


To the extent that the voters chunk in this manner, it seems to be 
personalized enough that the system doesn't degrade into party list 
(except in places where full ranking is enforced), yet it makes the 
burden easier to the point that ranked multimember voting does work.

I think that is most unlikely.  The only party that would likely nominate five 
candidates would be one that had reason to believe it
could win at least four of the five seats in the multi-member district.  
Parties that might have an expectation of winning two seats
would likely nominate only three candidates.  Parties that expected to win only 
one seat would nominate at most two candidates, and
based on our experience here in Scotland, many would nominate only one.

So the total number of candidates in a 5-member district would almost certainly 
be far short of 50I think a total of 20 would be
much more likely.



Here's some data from last parliamentary elections in Finland.

The largest multi-member district had 35 representatives and 405 candidates. 
All the large parties had 35 candidates. The largest
party got 11 representatives.

The two smallest multi-member districts had 6 representatives and 94 or 108 
candidates. 

One of the parties grew from 5 representatives to 39 representatives. So it 
needed lots of candidates too in order to not run out of
candidates in some districts.

(see http://en.wikipedia.org/wiki/Finnish_parliamentary_election,_2011)

If one has only one or two candidates more than the number of representatives 
that this party has or expects to get, then the
decision on who will be elected will be mainly made by the party and not by the 
voters. Preliminaries could help a bit by allowing
at least the party members to influence.

If proportional results are counted separately at each district, then it would 
be good to have a large number of representatives per
district to achieve accurate proportionality. In order to allow the voters to 
decide who will be elected there should be maybe twice
as many candidates per each party as that party will get representatives. In 
that way no seats are safe.

It is also good if there are such candidates that are not likely to be elected 
this time but that may gain popularity in these
elections and become elected in the next elections. All this sums up to quite a 
large number of candidates.

My favourite approach to implementing ranked style voting in this kind of 
environments would be to combine party affiliation and
rankings somehow. The idea is that even a bullet vote or a short ranked vote 
would be counted for the party by default. If one looks
this from the open list method point of view, this could mean just allowing the 
voter to rank few candidates instead of naming only
one. Already ability to rank three candidates would make party internal 
proportionality in open list methods much better. Probably
there is typically no very widespread need to rank candidates of different 
parties in this kind of elections, but it ok to support
also this if the method and the requirement of simplicity of voting do allow 
that. From STV point of view the problem is how to
allow better proportionality and voter decisions instead of party decisions in 
some nice way.

I just wanted to point out that actually one can come from open lists towards 
STV, and from STV towards a party based system with multiple candidates and end 
up pretty much at the same point.

 Hi Jameson,

 I looked over it.  I didn't see any technical problems immediately, but
 I'm going to try to re-read it a few more times and keep thinking it over.
  My emotional response, though, is that it's probably beyond the complexity
 limit for actual implementation anytime soon.  The idea that candidates
 from your district are in a bigger font and candidates outside your
 co-districts aren't listed at all but you can write them in is a clever
 trick, but I don't know if people will go for it.


 (Note: I've renamed co-district as super-district)

 The super-district idea and ballot design are not fundamental. For
 simplicity, it would work fine if only the candidates from your local
 district were available, as long as you could write-in candidates from other
 districts.


 Clarification on terminology: When you say Fair Representation, is that
 the same thing as Fair Majority Voting?


 Yes. Oops. I'd already fixed this error on the page.


 - I know Fair Majority Voting from here:
 http://mathaware.org/mam/08/EliminateGerrymandering.pdf
 - I know Balinski has a more complicated system that allows multiple
 winners per district.  I forget what it's called, biproportional
 apportionment, maybe?


 Don't know that one. Can you find a link?


 Here are some references:

 (Paywalled: http://www.springerlink.com/content/g21l8t2t12p4n14l/)


At a quick read, this is basically just a prettier formalism for FMV. Yes,
it is good math; no, it is not a politically- or legally-significant
change.

Oh, wait... it also allows multi-member districts. But not post-hoc
overlapping districts as in PAL.

 Gerechtigkeit,” Spektrum der
 Wissenschaft, April 2007, 76-80.

 (http://www.math.uni-augsburg.de/stochastik/pukelsheim/2006d.pdf)


This appears to use the prettier formalism to discuss a
multi-member-district FMV-like system in Zurich.

See also: S. Maier, P. Zachariassen, and M. Zachariasen, “Divisor-based
biproportional apportionment in electoral systems: A real-life benchmark
study,” *Management Science* 56, no. 2 (2010): 373–387.

This looks at algorithm performance and result quality (over several
measures) in the general problem of multi-member districts and global
proportionality, for various sources of real-world and simulated (including
deliberately pathological) data.

All of the above have the same problem I see with FMV: in the
single-member-district case, they could elect a minority candidate over the
majority candidate for that district. PAL resolves this problem by making
vote transfers explicit and, from the voter's point of view, optional and
thus intentional. Thus PAL elects winners as if it were a single-member
biproportional system, but it provides a much clearer rationale for the
discordant district-level results: the loser may have gotten more direct
votes, but the winner got a higher direct+transferred total; and all winners
reached the same overall quota.

This is the main idea of PAL.

OK, I'm turning into a bit of a spammer on this issue, but...

Here's some discussion of PAL representation's legality in the
UShttp://wiki.electorama.com/wiki/PAL_representation#Note_on_legality_in_US.
A state could pass a law to use FMV (a true proportional system) until the
anti-PR federal law is repealed, then automatically switch to PAL
representation (an easy and smooth transition; FMV was a major inspiration
for PAL). Basically, I think it's an important fact that FMV is the only
known proportional system *compatible with current US federal law*. (There
are no US constitutional barriers to PR, just federal law).

Jameson,

I believe the federal law applies only to federal elections. Thus a
state could allocate its state legislative seats proportionately in
any fair way that did not violate other laws.  In general, Congress
only passes electoral laws pertaining to federal elections. Isn't that
so?

I did not realize that Jefferson supported a proportional system of
electing representatives.
