ELIMINATION ROUND
COMPLETE
Below are the calculated sums of the pairwise differences of Percentage Value of a Delegate for each possible apportionment of 10 delegates among the 2 remaining candidates. The apportionment with the smallest sum (listed first) should be chosen. Accordingly, Hawkins is awarded 7 half votes, and Hunter is awarded 3 half votes.

****************
PROCEDURES
The GPVA presidential primary is held in presidential election years to determine who our delegates to the Presidential Nominating Convention will vote for on the first ballot. (This year we are apportioned 5 PNC delegates.) The primary is to be conducted as follows.
1. Voting is open to any permanent resident of Virginia who identifies as a Green by registering on the GPVA website. The opportunity to vote will be broadcast on all available media, including social media, through our locals, and through our list-serves and internal email lists.
2. The vote itself will be conducted on OpaVote.com, an independent and reputable online voting website. Voters will obtain a unique-to-them voter code by requesting it through a form on the GPVA website. They must be logged in to do this, and provide both an email and a physical address. A link will be emailed to them that can be used to cast a vote on OpaVote.com. Neither registration nor any information other than the voter code will be required of them on OpaVote.com. They will also be provided with information on the candidates, including which ones are officially recognized candidates, who will have an asterisk after their name on the ballot. The information provided will include the criteria for official recognition, a history of the interactions the candidates have had with GPVA or its members and officers, and any relevant information about their known interactions with other Green Party members around the country. Voters wishing to include a write-in candidate(s) not on the official ballot will be asked to email their ranked choices directly to the GPVA General Secretary, rather than casting their vote on OpaVote.
3. The ballot will list the three candidates who are officially recognized by the GPUS Presidential Campaign Support Committee, and other active candidates listed as such by that committee. The officially recognized candidates will be listed first, in alphabetical order, with an asterisk after their name, and the remaining candidates after, also in alphabetical order (by last name). The ballot will permit voters to rank some, none, or all of the candidates.
4. At the conclusion of the voting period the GPVA General Secretary will download the ballots, and will then apply the following algorithm to determine the apportionment of delegates to the candidates:
a. Calculate the percentage of "firsts" that each candidate got. Divide each candidate's "first" percentage by the lowest one, rounding down. For instance, if Candidate A got 32% of the firsts and the lowest candidate, Candidate B, got 3% of the firsts, then we calculate 32 divided by 3 equals 10 (and discard the remainder). This is done for each candidate.
b. Add up all the numbers. If the result is more than twice the number of GPVA PNC delegates, then drop the lowest candidate from all the ballots, so that the second-place choice (if any) for those who placed the eliminated candidate first becomes their new first-place choice. (We use twice the number of delegates because on the first PNC ballot half votes are permitted, i.e., a delegate may split their vote between two candidates.)
c. Repeat (a) and (b) until the result calculated in (b) is less than or equal to twice the number of GPVA PNC delegates.
d. Apportion the GPVA PNC delegates among the remaining candidates in such a way as to minimize the differences in percentage-value-of-a-delegate (PVD) among the candidates. This is achieved by taking the percentage of firsts that a candidate has and dividing it by the number of half-delegates they get. That's the PVD for that candidate. Calculate the pairwise differences in PVD's among the candidates. The delegates are to be awarded in such a way as to minimize the sum of these differences. In the extremely unlikely event of a tie, the GPVA co-chairs will determine the outcome by a coin-toss or other random method.
5. The election period is to be for exactly one week, starting at midnighton a Sunday. At least two weeks must be allowed to notify Virginia Greens of the election before voting commences.
6. The General Secretary will publish the ballots, the detailed results of their calculations, and the delegate apportionment to the GPVA membership within 3 days of the end of voting.
