PLACE voting details
PLACE voting stands for "proportional, locally-accountable, candidate endorsement voting". It is a proportional voting method for electing legislators to a multi-seat body. Like GOLD voting, Its main advantages are: simple ballots, minimal wasted votes, and "do no harm" (that is, it doesn't change FPTP outcomes unless they're non-proportional).
It assumes the voters have been divided up into one equal-population riding (aka district or constituency) per seat being elected. Precisely one representative per area (riding, riding, or constituency) will win. Rules for parties to nominate candidates for each district are outside the scope of PLACE.
- Before the election, candidates may endorse other candidates. From the perspective of candidate X in party Y, this divides other candidates into 4 groups. In descending order of preference, these are:
- "Same faction": those X endorses who are in party Y
- "Same party": those who are in party Y but who don't get endorsed by X.
- "Allies": Those X endorses who are not in party Y
- "Opponents": Those not in party Y who are not endorsed by X.
- The ballot lists the candidates running locally, and also has a write-in slot for each party. You can choose a local candidate, choose a party, or choose a party and write in a candidate from another district.
- Ballots are tallied, and any candidate who got less than 25% of the local vote is eliminated (unless they got more local votes than any other).
- Votes for eliminated candidates are transferred. They go first to "same faction", in descending order of raw vote total; then "Same party", again by vote total; and finally to "allies", again in vote order. If all these groups run out, a ballot is exhausted.
- Any candidate who gets a "quota" of votes wins, and the excess portion of all their votes (above what they needed to win) is transferred.
- A "quota" is defined as V/(S+1), where V is the total number of votes and S is the number of seats. So in an election for 9 seats, a quota would be 10% of the total votes, or 90% of the average district's votes.
- If one candidate got two quotas of votes, then half of each of those votes would be "excess" and would be transferred. Thus, transfers can involve partial votes.
- As soon as a candidate is elected, all other candidates in the same district are eliminated.
- Until all seats are full, the candidate that is farthest behind the frontrunner in their district is eliminated, one by one.
- Thus votes will move from weaker candidates to stronger ones until they make up full quotas and the seats fill up.
- Each winning party assigns each district where they did not win to one of their winning candidates as "extra constituents".
- Thus, even if your party did not win in your district, you will be a constituent for a representative from your party; you'll still have "your" representative to listen to your petitions.

Niggling detail 0: Endorsement rules
If a candidate has any within-party ("same faction") endorsements, he must have at least 3 of them (or at least half of the other candidates running in his party, rounded down; whichever is less). This helps prevent unserious candidates from running merely as "vote funnels" for a single specific serious candidate.
A candidate may endorse no more than half of all other candidates across all parties, and may not make more endorsements than the number of seats up for election (or 5, whichever is greater). This includes both within-party and out-of-party endorsements.
A candidate may reject an endorsement from another candidate. Rejected endorsements are not valid.
Niggling detail 1: Information available in the voting booth
Each voting booth will have:
- A list of all candidates in all districts (all eligible write-ins), along with lists of "faction" and "ally" endorsements for each.
- Exception: in elections involving 30 seats or more, districts may be aggregated into "megadistricts" of less than 30 districts each, and information provided only for candidates within the local "megadistrict". Candidates outside the "megadistrict" are still valid write-ins; the grouping only affects the information provided in the booth.
- The "faction" information for each party will also be available in the form of a matrix, where columns are endorsers and rows are endorsees, and "similar" candidates (those getting correlated endorsements) are listed near to each other. Rows and columns will use the same ordering of course. There will be one matrix per party, so the maximum size of a matrix would be 29x29.
- Each eligible write-in candidate will have an optional error-resistant 3-letter code, for people who can't spell their name.
- Each candidate will be allowed to submit a brief under-50-word statement which will go with their name
- An explanation of the PLACE rules, with appropriate examples (similar to this FAQ)
Niggling detail 3: Elimination and the 25% threshold
If a candidate gets more than 25% of the local vote, and/or the most votes, from a district where they are not running, they will not be eliminated, and will be considered to be running in all districts in which they passed the threshold. In that case, they will not be eliminated as long as they would survive in one of those districts. For instance, even if one of those seats is filled, they will not be eliminated until they all are.
Niggling detail 4: Ties and Simultaneous Winners
In the rare case that several candidates from separate ridings reach a full quota at the same time, the one with the fewest local votes is elected first, to allow the others to possibly accumulate a bigger surplus before winning. In the even rarer case that more than one candidate from the same riding reach a full quota at the same time, the one with more local votes is elected.
In other cases of ties, they are resolved by initial vote totals, or if that doesn't break the tie, randomly (by drawing lots or some other random procedure).
Niggling detail 5: Independent candidates
All independent candidates are considered to be different parties for the purposes of the "same party" grouping, but the same party for the purposes of the "same faction" grouping. The upshot is that a vote for an independent candidate will go first to other independents she endorsed, then to non-independents she endorsed, then will be exhausted. It will never go to other independents she did not endorse.
Niggling detail 6: Extra territory
Parties are required to assign extra territory in such a way that roughly balances the total party vote for each candidate's full territory. That is to say, it should be impossible to improve that balance by changing the assignment of a single district. Aside from that, they are encouraged to respect geographic or demographic communities when assigning extra territory.
Proportional or semiproportional?
PLACE is proportional in a two-party context. If there are more than two parties, though, it is only semiproportional; smaller parties without a clear regional character may get less than their proportional share. But if that happens, their votes will not be ignored; they will have a say on which of the larger parties gets more seats, and even on which candidates from that allied larger party win. Thus, a smaller party will be able to promote their issues by favoring those candidates who prioritize those issues. Also, if there are two competing party coalitions, with all voters choosing one of the alliances and all candidates preferring same-coalition candidates over opposite-coalition ones, then this will be fully proportional between the two coalitions.
Note that other proportional voting methods sometimes are used with extra rules designed to stop fringe parties from winning seats. For instance, in the German mixed-member "proportional" method, a party that gets less than 5% or 2 direct seats does not get a proportional allotment of seats. Thus, technically speaking, even the German system is really only semiproportional, not truly proportional.
The advantages of this method are as follows. First, the advantages common to all proportional representation methods:
- Equality: partisan gerrymandering is impossible, and each party gets its fair share of seats.
- Representation: Almost all voters are truly represented; even if you are a minority in your riding, your vote helps elect a candidate of a party you sympathize with.
This method also keeps all the strong points of the current voting system. (The current system is horrible in general, but it still has its strong points.)
- Simplicity: you just choose one candidate, and the ballot is short.
- Accountability: voters, not parties, choose who is elected.
- Unity: discourages splinter parties, because candidates without a strong local base of support are eliminated up-front.
- Geography: Everyone has a representative who lives relatively close to them.
GOLD voting: An older, slightly more complex version of PLACE.
OL/D voting: similar to GOLD, but without the constraint of one candidate per riding, and with a slightly weaker elimination rule.
PACE voting: a similar system, for a nonpartisan context without ridings.
SPACE voting: a summable version of PACE; simpler for voters, but more complex in terms of vote-counting.
Proportional 3RD voting: an old version of PACE.
- Candidate endorsements should offer at least two levels (endorsed or unendorsed) and should take account of party. I think that 2 levels of endorsement (endorsed or not) at 2 levels of party sameness (same or not) is a good amount. The method would work with as few as 2 levels and there could be a rule for the order between "unendorsed same party" and "endorsed different party". So simplification is possible on this but not much.
- Voting for either a same-district candidate or writing in an other-district candidate is pretty fundamental to the method. Leaving out the "do not delegate" option would not break outcomes but might be a deal-breaker for some voters so I think it's worth keeping it. Leaving out the "write in party only" option would change little.
- I do not see a way to further simplify the transformation into a preference ballot.
- The pre-elimination step could be simplified to "eliminate all but top 2". This would make outcomes marginally worse in rare cases but is not a big deal.
- The STV transfer process is already as simple as possible.
- Assigning extra district is cosmetic, so it would be fine to skip this step. Still, it emphasizes the fact that even those who do not win locally are still represented, so I think it's worth it.
