(→‎Procedure: Simplified the procedure. Wanted to not use the term "delegate" for the candidate-to-candidate transfers in step 3.)
Line 5:
 
 
'''1. Candidates publicly declare their delegationrankings orderof the other candidates'''
 
A) Before the election, all candidates must rank the other candidates (including declared write-ins) in order of preference. Equal rankings and truncation are allowed. The candidatecandidates's rankings are all made public. Later, in the "delegationcandidate voting" step, anycandidates delegationmay fromonly oneapprove candidateother mustcandidates bein consistenta withway that candidate'sis consistent with their rankings. This helps reduce the possibility of corrupt vote-selling or "smoke filled rooms".
 
'''2. Voters vote delegable plurality-style votes or non-delegable approval-style votes'''
 
A) Each voter submits an approval ballot. There is some way (such as an extra write-in slot) to vote for an invalid candidate named "do not delegate".
 
B) Any "bullet vote" - that is, a ballot which votes for only one candidate - is considered a "delegable vote" for a candidate., Theseunless votesthe arevoter talliedindicates forthat each candidate. Of course, any ballots which vote forit "doshould not delegate"be ordelegable. anyThese other invalid write-invotes are nottallied consideredfor aseach bullet votescandidate.
 
C) Approval totals for each candidate are also tallied. These preliminary results are announced, along with the number of "delegable votes" each candidate has.
Line 19:
D) If any candidate has an absolute majority at this point, or cannot possibly be beaten by any other candidate using the delegable votes and candidate rankings available, then they win immediately.
 
'''3. Candidates choose how to delegatecast their delegable votes publicly in accordance with theirthe delegationprescribed order'''
 
A) There is a brief period - perhaps a week - for candidates to analyse and negotiate based on these preliminary results. (Actually, the correct strategies for all candidates and the resulting winner will already be obvious. Usually, all candidates except this winner would concede as soon as preliminary results are announced. However, for the occasional candidate inclined to act irrationally in a way that matters - say, by not delegating to an ally, even though the alternative is to see an enemy elected - this interim period would give them a chance to rethink things and come into reason.)
 
B) All candidates, in descending order of the number of total votes they have, publiclychoose delegatehow many other candidates they want to approve with their own vote and the delegable votes they control; that is, they choose a number N, and their "delegable vote" total is added to the approval totals of their top N favorites as announced in step one. They may choose N=0 - that is, not delegateapprove theirany voteother to anyonecandidates. They may not choose N=(number of candidates) - that is, delegateapprove theirall votesother to everyonecandidates. If they declared a tie in their preferences, they must either delegate toapprove all candidates whom they included in that tie (as well as anyone they ranked above that), or none of them. (Note: Doing this in descending order prevents a weaker candidate from making an ultimatum to a stronger candidate, and thus strengthens the strategic equilibrium of any pairwise champion there is.) Votes may not be re-delegated.
