Simplified PLACE

From electowiki

Assuming that there is one equal-population district (aka riding or constituency) per seat, and that the parties have already nominated candidates by district, here are the steps:

  1. 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.
  2. 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).
  3. Votes for eliminated candidates are transferred. They go to candidates in the same party, in descending order of raw vote total.
  4. 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.
  5. 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.
  6. 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.

Compared to PLACE

This voting method is like PLACE, without endorsements. The problem is that votes for parties whose candidates are frequently eliminated by the 25% threshold can end up being wasted. Also, there is no ability for a leader of some community to run as an independent in order to negotiate for that community's interests with their endorsement power.

Nonetheless, this is a proportional method. Unlike PLACE voting, this is probably more favorable to existing large parties than other proportional representation methods.
