:'''''Draft
This set of rules is broken into three parts: 1) The goal of MAF, 2) the definition of "Pools" of candidates advanced to the general election in this system, and 3) the rules for populating the Pools of candidates. It is written with some effort toward legal precision and legal document tools-of-the-trade (e.g. the use of [http://lexicontools.com/defined_term.php capitalized "defined terms"]), but more work is needed.
Line 29:
#If there is one or more candidates in the Plurality Candidate Pool, attempt to add an equal number qualified candidates to the Opposition Candidate Pool, evaluating each Non-advanced Candidate using the following steps
#*4a. Find the Non-advanced Candidate with the highest approval score.
#**If this candidate has less than 40% approval,
#**If this candidate has greater than 40% approval, add this candidate to the Opposition Candidate Pool, then proceed to step 4b.
#*4b. Compare the size of the Plurality Candidate Pool and the Opposition Candidate Pool
#**If the Plurality Candidate Pool has more candidates than the Opposition Candidate Pool, skip back to step 3.
#**If the Opposition Candidate Pool contains an equal number of candidates to the Plurality Candidate Pool, proceed to step 5.
# If the Ballot Satisfaction Score is greater than 50%, skip to step 6. If the Ballot Satisfaction Score is under 50%, ensure at least two candidates advance to the general election using the following steps:
#Candidate selection is complete. Advance all candidates in the Supermajority Candidate Pool, the Plurality Candidate Pool, and the Opposition Candidate Pool to the general election.▼
#*5a. If there are no candidates in the Opposition Candidate Pool, find the Non-advanced Candidate with the highest approval score. If this candidate increases the Ballot Satisfaction Score by more than 10% (the "Candidate Differentiation Threshold"), add this candidate to the Opposition Candidate Pool, and skip to step 6. Otherwise, advanced to step 5b.
#*5b. Consider each Non-advanced Candidate in order of approval score. Find the first candidate who increases the Ballot Satisfaction Score by more than the Candidate Differentiation Threshold (10%), and add this candidate to the Opposition Candidate Pool, and skip to step 6. Otherwise, advance to step 5c.
#*5c. Find the Non-advanced Candidate with the highest approval rating. Add this candidate to the Opposition Candidate Pool, and advance to step 6.
▲# Candidate selection is complete. Advance all candidates in the Supermajority Candidate Pool, the Plurality Candidate Pool, and the Opposition Candidate Pool to the general election.
