PRIMARY ELECTION TERMINOLOGY

There are numerous variations of primary election rules which govern voter access. Because there are no unified standards, election law experts themselves often use conflicting terminology to describe the nature of certain primary elections. Below, we have listed the general categories of primaries with short descriptions of the labels we have selected to describe each system as they relate to a voter’s right to participate.

Are we missing something? Let us know.

Types of Partisan Primaries

Partisan Primaries serve the private purpose of selecting a nominee to represent a political party on the general election ballot. In a partisan primary, voters and candidates participate using different ballots for each party, subject to the access requirements generalized below.

Closed Primaries

A voter cannot participate in the nomination of party candidates unless they are registered members of that party.

Semi-Closed Primaries

A partisan primary system in which a political party has the option, but not obligation, to allow or disallow unaffiliated voters to participate.

Open Primaries

A partisan primary system in which a political party must allow unaffiliated voters to participate.

Semi-Open Primaries

A partisan primary system in which a voter, regardless of his or her party affiliation, can choose to participate in the party primary of their choice.

Nonpartisan Primary v. Jungle "Primary"

Primaries that serve the public purpose of narrowing the candidate field for the general election ballot. In a nonpartisan primary, all voters and candidates participate on the same ballot regardless of party affiliation.

All nonpartisan primaries are “open” because no voter or candidate is excluded on the basis of their party affiliation.

Nonpartisan Primaries

In a nonpartisan primary (also known as a voter-nominated primary), all candidates and voters participate on the same ballot and the top vote getters, regardless of party affiliation, advance to the general election.

A nonpartisan primary advances the top two or more vote getters, depending on the local rules. In California, for example, the top-two candidates advance to the general elections. In Alaska, for example, the top-four candidates advance to the general election.

Jungle Primary

Often confused with a “top-two” primary, a jungle primary is not actually a primary election. In fact, a jungle “primary” occurs on the same day as the general election, and if a candidate receives 50%+1 or more of the vote, the election is over and that candidate is elected.

In a jungle "primary", only if no candidate gets more than 50%+1 of the vote do the top-two candidates then participate in a head-to-head runoff election.
