[EM] Proportional election method needed for the Czech Green party - Council elections

[Peter Zbornik]

Hi,

I am a member of the Czech Green party, and we are giving our statutes
an overhaul.
We are a small parliamentary party with only some 2000 members.
Lately we have had quite some problems infighting due to the
winner-takes-it-all election methods used within the party.
I am sitting in the working-group for the new party statutes, and
would like introduce proportional elections instead.
So I thought I might find some help in this forum in formulating my proposal.

There are several practical different types of elections in the party,
which need to be addressed:
1. election of council members
2. election of delegates to regional and national rallies, where the
regional and national council members are elected
3. election of candidates to the ballot - primary elections

In this letter, I would like to ask you to propose good proportional
election system for the election of the council members.
A council exists at all levels in the party organization: national,
regional and local.

SCENARIO 1: COUNCIL ELECTIONS
We have to elect the following:
1. Election of the party president
2. Election of one or more vice-presidents in order of importance,
i.e. first vice president, second, third etc.
3. Election of the rest of the council members
Normally the council has five or seven members.

CURRENT SYSTEM:
Currently the president and the vice presidents are elected in several
two-round run-off elections
(http://en.wikipedia.org/wiki/Two-round_system).
The rest of the board members are elected by block-voting
(http://en.wikipedia.org/wiki/Plurality-at-large_voting) in the
following way:
1. A candidate who gets 50% of the vote is elected
2. In the second round, candidates with less than 25% of the votes are
eliminated
3. In the third round, candidates with less than 30% of the votes are
eliminated. Now only 40% of the votes is enough for election.
4. New elections are arranged for the rest of the mandates, where
candidates who got at least 20% of the votes in the previous election
rounds can run as candidates in new elections:


DELIVERABLES FOR IMPLEMENTATION:
In the end, if proportional elections are to make their way into the
party statutesm, then I have to deliver the following:
1. a proposal of a text to the statutes, describing the election rules
and procedures
2. a motivation of the proposal which shows why it is better than the
present one.
3. a vote counting computer program which works
4. preferably a ballot scanning program
5. preferably some good examples that the system works in real life.

CRITERIA:
I am looking for a approximately proportional election scheme, which is
(i) simple for the party members to understand - this is the main
criterion. A complex system like Schulze-STV has no chance of getting
required political support
(ii) simple to use, i.e. where it is quick to vote and vote counting
is also quick (max 400 votes cast)
(iii) gives results which leave most party members reasonably
satisfied with the result
(iv) votes are cast "secretly" on paper ballots, alternatively on some
smart electronic voting system that is as secure as paper ballot
voting.
(v) asset voting is excluded due to lack of political support

ASSUMPTIONS:
There are several types of board elections in the party, where several
types of assumptions apply:
1] 70-90% of the voters are "dishonest" - i.e. they vote strategically
as they are told by leaders, who want to maximize the number of
"their" people on the board - this is the case for the election of the
national party board
2] 30-60% of the voters are "dishonest" - the roughly regional election case
3] 20% of the voters are "dishonest" - this is roughly the local election case

Currently I am considering Re-weighted range voting and range voting,
since it fulfills the criteria above, but other simple-to-understand
methods could be used.
Maybe the RRV system will have be reduced to approval voting for the
high dishonesty scenario.
This would lower its attractivity.
A contender to the RRV-range voting system is the STV-IRV system used
by the green party of the USA, since it evidently works, but is more
difficult to understand than RRV: see
http://www.gp.org/documents/rules.shtml#section7

QUESTIONS:
Please propose a voting system fulfilling the criteria above with the
given assumptions, and answer the following questions:

1. if the proposed election system is as simple to understand as RRV
and range voting,
name what advantages and disadvantages it has to RRV and range voting.
Alternatively, which specific variant of RRV and range voting do you
recommend for the elections described above (normalization of voter
scores, number of categories, given that 70-90% of the voters vote
strategically)?
To clarify: Asset voting is excluded for this election type, since we
have problems with transparency and political support.

2. In which order should the election of the board members be
performed in order to insure that all the voters will be reasonably
satisfied with.
a] how should the elections be done, it the current election order
should be preserved (i.e. first you elect the president, then the vice
presidents etc.)?

b] Is one election enough to give an unambiguous winner, even if the
president is elected by the margin of one vote?
The talk about RRV not electing the Condorcet winner makes me a little nervous.
The election of the president has to be unambiguous, and several
elections is not a problem.

c] if you reverse the election order, i.e. first you elect the board
members, then the president and the vice presidents, and lastly you
elect the president? This order of election seems to be more simple to
conceptualize.

d] what are the main advantages of the your preferred method to the
current election system?

e] (optional question) if a member of the board leaves his/her
position before the end of the election period, and a new member of
the organ has to be elected, how should this election take place in
order to insure proportionality is retained?

Specific questions for RRV:
f] what is the minimal number of votes a person needs in order to be
elected (if all voters except for one put an "X" for the candidate and
the last voter puts maximum points, is this candidate normally
elected?)

3. If the following exists for your selected election method, could
you please provide a reference to:
a] a text which describes the election procedure and can be used in
statutes (preferably a text in existing statutes)
b] an explanation of how the voting system works and an explanation of
the vote counting procedure for a person who knows nothing about
election methods. For RRV I do not understand the d'Hondt style
re-weighting. Why d'Hondt? Why does it give proportional
representation?
c] an open-source program for windows which makes it easy to count the
votes, once you have entered the data in the computer.
d] a list of organizations, which use the method

4. As we have to count the ballots quickly, I would appreciate a tip
on the following:
a] A tip of a good and cheap and open source system for creating and
digitalizing paper ballots.
b] Alternatively a free electronic voting system with the same
security level as a paper ballot system could be used, preferably with
paper ballot receipts, which would be counted later for confirmation
of the vote.
If you know of any such system, please let me know.

OK, that's the first scenario.
Any help answering some of the questions above is greatly appreciated.

Peter
