Methods for tallying votes to determine a primary election's outcome include plurality counts and majority counts.
In plurality systems, the candidate who wins the largest share of the vote wins the election. The candidate need not win an outright majority to advance from the primary. These systems are sometimes referred to as first-past-the-post or winner-take-all. Top-two primaries and other versions of this system, such as top-four or top-five, are a specific type of plurality system where all candidates are listed on the same ballot, regardless of party, and a pre-determined number of the highest vote-getters advance to the general election.
In majority systems, a candidate must win more than 50 percent of the vote in order to win election and advance from a primary. In the event that no candidate wins an outright majority, a runoff election is held between the top two vote-getters. For this reason, majority systems are sometimes referred to as two-round systems. Ranked-choice voting is a specific type of majority voting system that may also be used in primary elections.[1][2]
This article details primary election vote requirements by state for state-level and congressional primary elections.[3][4]
