Line 13:
After the winner of the district's first seat is identified, the following steps calculate which candidate wins the second seat.
# Identify the ballots that rank the first-seat winner as their first — highest-ranked — choice. (If there are no such ballots, no ballots will be ignored in the next step.)
# Completely ignore the ballots identified in step 1, and use the remaining ballots to identify the most popular candidate from among the remaining candidates. (If no ballots were identified in step 1, then use all the ballots.) This candidate will not necessarily be the second-seat winner. Instead, this candidate is used in step 4 to identify which ballots are from voters who are well-represented by the first-seat winner.
# Again consider all the ballots.
# Identify the ballots in which the first-seat winner is preferred over the candidate identified in step 2. This step identifies the ballots from voters who are well-represented by the first-seat winner. Note that the only way for a voter to avoid having his or her ballot identified in this step is to express a preference that significantly reduces the chances that the preferred candidate will be ranked as most popular.
# Proportionally reduce the influence of the ballots identified in step 4. (This step reduces the influence of the voters who are well-represented by the first-most representative choice.) This calculation uses the following sub-steps:
## Count the number of ballots that were identified in step 4.
## Subtract half the number of total ballots.
