'''VoteFair party ranking''' is a vote-counting method that identifies the popularity of political parties for the purpose of identifying how many candidates each political party is allowed to offer in a non-primary election. This limit is useful in elections that otherwise would attract candidates from very unpopular parties. It allows, and encourages, two or three candidates from the two most popular parties.
 
== Purpose and usage ==
This method is designed for use in high-level elections that otherwise would attract too many candidates from political parties that are so unpopular that their candidates have almost no chance of winning. This limit enables voters to focus attention on all the candidates, which becomes important when elections use [[Ranked ballot|ranked ballots]] or [[Score voting|score ballots]] instead of [[Single-mark ballot|single-mark ballots]].
 
Rules for ranking the parties by popularity include:
Any single-winner vote-counting method that uses ranked ballots and pairwise counting can identify the most popular party. [[VoteFair representation ranking]] identifies the second-most popular party in a way that proportionally reduces the influence of the ballots that identified the most popular party.
 
* Any single-winner vote-counting method that uses ranked ballots and pairwise counting can identify the most popular party.
The third-most popular party is identified after appropriately reducing the influence of the voters who are well-represented by the first-ranked and second-ranked parties.  Without this adjustment the same voters who are well-represented by one of the most popular parties could create a "shadow" party that occupies the third position, which would block smaller parties from that third position.

The rules for limiting the number of candidates from each party are:
The most popular party and the second-most popular party would be allowed two, or possibly three, candidates each. A few of the next-most popular parties would be allowed one candidate each. The remaining parties would not be allowed any candidates in that contest.
 
* The most popular party and the second-most popular party would beare allowed two, or possibly three, candidates each. A few of the next-most popular parties would beare allowed one candidate each. The remaining parties wouldare not be allowed any candidates in that contest.
* The total number of candidates in a contest would beare limited to a specific number, such as seven candidates. This limit can be different for different political positions.
* If any parties offer fewer candidates than they are allowed to offer, then lower-ranked parties that otherwise would not be allowed to offer even one candidate would beare allowed to offer one candidate each. This provision discourages a popular party from forcing the voters in that party to elect a candidate who would lose against a more popular candidate from the same party.
* If either of the top two parties conducts their primary election using [[Single-mark ballot|single-mark ballots]] then that party is allowed three candidates instead of two candidates, and the third-most popular party is allowed two candidates instead of one candidate.
 
When a party rises in popularity and earns an additional place on the ballot, that is offset by another party losing a position on the ballot.

If a party splits into two parties in an attempt to offer more candidates, both parties are likely to lose popularity because fewer voters will rank each one at the top of their ballot.

During a previous election, ballots must ask the voters to rank the political parties. The advance results enable candidates and parties to know how many candidates that party can offer in each contest in the upcoming election cycle.
