The Alaskan Top Four Model & iEBs
-
@gregw said in The Alaskan Top Four Model & iEBs:
Yes. The various organizations promoting Top Four Primaries are proposing a "choose one" vote for the first round. I would like to offer something better.
Approval, for example, would be better than Choose-one Plurality. And it would be easier to explain to people than a PR system. It could be improved later, after people have become used to equality.

@cfrank said in Before a Real Runoff:
@jack-waugh I don’t know much about PR, but this is an attempt to balance seats by considering party affiliations without stuffing clones. Can PR be improved with “Cake Cutting” incentives?
I should think that a system that does not refer to parties would work better. Simplicity is probably necessary for selling it.
Maybe Reweighted Range Voting (RRV) using the same kind of ballots (maybe Approval) as the final will use. In PR discussions, when I have brought up RRV, the PR mavens have told me that it's not one of the best options. But they don't seem to be here today, so I'm hoisting RRV up the flagpole.
-
Another option for the first round of balloting and tallying is Asset Voting. Each candidate gets points for how many voters approved hir. The candidate having the least support gets to distribute it to whichever other candidates se chooses. Repeat this until the number of candidates is the number for the final plus one. Send the ones with the most support then on to the final.

Your advocacy is elegant, I will change the opening as follows but leave the rest alone.
In support of replacing Plurality Voting with Approval Voting, eminent election scientist Jack Waugh asserts our right to better voting systems:
A voter should be the one to determine which candidates her or his vote supports and opposes. Plurality Voting does not respect this right. In an N-candidate election for a single seat or office, voters who want to oppose fewer than N - 1 are told to lump it. They are denied the right to cast a vote that reflects their political judgment.
I came up with a short version I will use on my plurality voting page:
As voters, we should have the right to choose which candidates we support or oppose. Plurality Voting does not respect this right; we can only support one candidate and oppose the rest.
Some voters are happy to support only one candidate, they will choose the lesser of two evils and call it democracy. They have the right to vote as they will, but the rest of us suffer under their limit. Should we not have the same right to vote as we will?
Voters Take Charge was created to demand that our right to vote as we choose is fulfilled. We are even more subversive; we want an election system that puts voters in control of public policy. Therefore, we demand Proportional Representation and better voting systems for single-winner elections.
Lime also suggest RRV, definitely better than STV.
Ambassador quotas and asset voting are both fascinating ideas. I can see running both up the flagpole in the future.
I am also tempted to propose something akin to DPR voting (Direct Party and Representative Voting) on steroids. Take a PR election in a five-member district; at stake are the district’s votes in the legislature, which are equal to the population of the district. The top five candidates split the district's votes based on the percentage of the vote each candidate received. The legislature would need to rewrite its rules of operation. That is a feature, not a bug.
For now I will go with your suggestion of Approval Voting for the first round of a Top Five election. Simple and fair.
I recently voted in a nonpartisan mayoral election with seventeen similar candidates and a top two runoff. Top five with approval voting would have helped. But next time I'm just going to vote for the candidate that uses the phrase "multi-modal transportation" least often. A multi-modal transportation boondoggle exists about 150 feet from my back door.
-
I'm not an election scientist, let alone an eminent one, more of a voting-systems enthusiast. Anyway, I don't need you to credit me for those words of advocacy.
Regarding "Plurality", note that Approval is decided by plurality. That's why I call FPtP "Choose-one Plurality Voting".
-
In regard to control of pubic policy, look up "Liquid Democracy".
Approval-ordered Llull (letter grades) [10], Score // Llull [9], Score, STAR, Approval, other rated Condorcet [8]; equal-ranked Condorcet [4]; strictly-ranked Condorcet [3]; everything else [0].
-
Liquid Democracy would be exciting and much more direct than ballot initiatives. It would drive party leaders nuts.
I would love for a few small but real governments to give it a try.

Smaller than the State of Rhode Island And Providence Plantatations?

I was thinking in terms of a small municipality, but if Rhode Island wants to go for it, great!

Before I look into the rest of the stuff in this thread, I notice that RRV has been mentioned a few times. This is a score conversion of Thiele's Proportional Approval Voting, or PAV. However, I do not think it is the best conversion. The method known as Sequential Proportional Score Voting (SPSV) has better criterion compliance (it passes the additive and multiplicative versions of scale invariance*), and is no more complex.
*Basically if you multiply all scores by a constant and/or add a constant to all scores, the result remains unchanged.
-
@toby-pereira said in The Alaskan Top Four Model & iEBs:
score conversion
might not be necessary. Approval ballots might suffice. So, everywhere that I mentioned RRV (out of admitted ignorance), consider PAV instead.
-
But now, I see that PAV is hard to calculate. So, I don't know. I'm just suggesting that rather than top-four or top-five, maybe some calculation can be used so as to reduce the number of likely clones that make it through. Of course, one candidate from each clone family should be permitted, with sufficient support.
-
I've read through this thread a bit more now. So we first want an election (with potentially quite a lot of candidates standing), where we select four candidates to go into round 2 for the election to determine the winner.
If there might be a lot of candidates standing in round 1, then to keep it simple, I would definitely recommend some form approval voting. However, under normal approval voting there is the possibility of the top four being blocked out by clones, so it might make sense to use a sequential proportional method. SPAV, the sequential version of PAV, I think would be ideal for this. It shouldn't be hard to calculate when done sequentially (in response to Jack).
PAV-based methods often aren't recommended for proportional elections because PAV isn't exactly proportional and has some failure cases. However, I don't see that as a problem here. This isn't meant to be an exactly proportional election. It's just to prevent multiple clones appearing on the final ballot. (S)PAV has better monotonicity properties than most other proportional methods - e.g. Phragmén or quota-based methods. SPAV also has a simple algorithm. Phragmén wouldn't be awful for this either, but I wouldn't recommend a method that deals with quotas.
Then for the final ballot, it's a case of what's your favourite single-winner method. And that's the big debate.

@gregw said in The Alaskan Top Four Model & iEBs:
Thank you for the help! Especially for telling me about RRV. Much better STV. I think I might be able to simplify the explanation.
You're welcome! You can find other proportional cardinal systems by looking up
approval-based committee voting. (The extension to score voting is usually very simple.)I have been working on a page that explains a MMP system that elects representatives from single member districts with a pretty accurate proportionality and a minimum number of at-large seats. The downsides of course are not easy to explain and the legislature would have a different number of seats after each election. But people, especially incumbents, do like their single member districts. Should I post it on this forum when I am finished?
This would be great!
I'd suggest taking a look at biproportional representation as well; it's the current state-of-the-art for proportionally allocating seats between parties. It fixes most of the issues associated with mixed-member proportional as well: voters choose candidates instead of parties, all candidates have their own district(s) instead of having 2 separate classes, etc.
I do like Ranked Robin but it will be a bit of a challenge to explain. It needs a video and a name change to Round Robin, I saw that somewhere I think they are the same, yes? Should not let it be confused with Ranked Choice Voting.
Would be nice to see a better explanation for sure! The traditional name is "Condorcet methods", but really they should just be called "majority vote" (since the candidate with a majority over every other wins).
Would you say that the strategy concerns with Score are not so serious that an Automatic Runoff is needed?
Probably not, because strategic score ends up being equivalent to approval (which is already well-regarded as a system).
I did notice a chart that said Score does not have a clone problem but STAR does. Is that correct?
In theory, yes. In practice, STAR is interesting because it intentionally fails clone-independence to encourage a better outcome. The optimal strategy for STAR is to have every party run at least two candidates, so they can lock up both spots in the runoff. This gives each voter multiple choices they can feel comfortable with.
As an example, I'd prefer a situation where both Biden and Kamala Harris were listed separately on the ballot so I could rank Harris higher (and help her win the runoff). Right now I'm not very happy with any of the candidates in the race. On a simple left-right scale I'm close to Biden, but I would much prefer to vote for someone younger. With STAR, every voter has at least two choices they think are tolerable.
Generally I think of STAR as just reversing the primary-then-general order: we have a general election to choose the best party (the score round), and then a "primary" where we pick the best nominee by a simple majority.
Will the Alaskan Top Four model produce a lot of clones?
Not sure what you mean. The Alaska top-4 model has a disadvantage of failing clone-independence, because clones split the vote in the first round. (Which kinda sucks, because one of the few advantages of IRV over FPP is it's immune to clones in theory.)

@toby-pereira
Great job of reading my mind, I was thinking about Approval leading to block voting last night.SPAV is very interesting, the KP transformation is ingenious.
I am trying to figure it out, towards that goal I visited Sequential proportional approval voting
and downloaded
The Excess Method: A Multiwinner Approval Voting Procedure to Allocate Wasted VotesDon’t be surprised If I have more questions
I should clarify what I am trying to do.
I want to propose an alternative to the nonpartisan Top four systems currently being promoted by the friends of independent candidates. This was also inspired by a 17 candidate mayoral election I recently voted in.It would work like this:
- A state run party primary with four options for each party: open, semi-open, closed, or do it yourself.
- If there eight or more candidates a round to narrow the field to five candidates.
- A final round with a good voting system.

@lime

I have looked at biproportional representation, I think it would be great, but I don’t think I can sell it. It would be beyond my powers of creating simple, concise explanations.
Round Robin Majority Vote might be a good name. Descriptive, all four words are friendly and/or positive. RRMV is a pretty good acronym.
In theory, yes. In practice, STAR is interesting because it intentionally fails clone-independence to encourage a better outcome. The optimal strategy for STAR is to have every party run at least two candidates, so they can lock up both spots in the runoff. This gives each voter multiple choices they can feel comfortable with.

Generally I think of STAR as just reversing the primary-then-general order: we have a general election to choose the best party (the score round), and then a "primary" where we pick the best nominee by a simple majority.Would California be wise to replace their two round top two system with STAR?
Does STAR work well in elections with many candidates? Like the recent 17 candidate Denver mayoral election?

Not sure what you mean. The Alaska top-4 model has a disadvantage of failing clone-independence, because clones split the vote in the first round. (Which kinda sucks, because one of the few advantages of IRV over FPP is it's immune to clones in theory.)
I am trying to decide what would be a good voting method to use in the first round of a two round system, with the first round having 8 or more candidates. The big issue is how to deal with clones.

Then the best system is probably some kind of proportional representation algorithm. That said, I'm not sure why having separate primaries is necessary (most countries and don't have anything like that). I think it would be better to just set a requirement for a fixed number of signatures, donors, and/or endorsement(s) from registered parties to get on the ballot.
(Honestly, I think the main reason IRV uses a 4-candidate primary is that failures like nonmonotonic elections become more common the more candidates you have. Using a top-4 primary makes it easy to sweep those failures under the rug.)

You are right, primaries are not necessary, however they are traditional.
I also have practical reasons:
Eliminating primaries would generate opposition and negative publicity.
By giving political parties primary options, (closed, semi-open, open & do it yourself) I hope that parties will be more receptive to my proposal, at least in comparison to the non-partisan proposals.
Primaries serve to bring public attention and participation to parties' nominating processes. This could be a big help for third-parties if there are reasonably low barriers to primary participation.Parties are inevitable in a democratic system, and serve important purposes. We need competition between more strong parties.

I bet you are right.

Both SPAV Sequential proportional approval voting and the Excess Method
The Excess Method: A Multiwinner Approval Voting Procedure to Allocate Wasted Votes
would work well in narrow down the field in large elections.SPAV is a lot easier to count and explain and should work quite well.
The Excess Method adds calculations after the election of each candidate to distribute the seat winning candidate's excess approvals. This will, at least in theory, better represent the will of the voters. With the Excess Method, voters could approve all the candidates they like with no concern for strategy or temptation to tactical vote.
A difficult decision. Do you have a dog in this race?
