Primary elections allow voters to determine which candidates compete in the general election and can be nonpartisan or partisan. In partisan primaries, voters choose the candidates they prefer for a political party to nominate in the general election.

The laws governing primary elections vary from state to state and can even vary within states by locality and political party. For example, only registered party members are allowed to vote in closed primaries, while registered party members and unaffiliated voters are allowed to vote in semi-closed primaries, and all voters are allowed to vote in open primaries.

Primary elections also vary by the way their outcomes are determined. Majority systems require the winning candidate to receive at least fifty percent of the votes cast, while plurality systems do not. In top-two primaries, top-four primaries, and blanket primaries, all candidates are listed on the same ballot, regardless of partisan affiliation.

HIGHLIGHTS

* New Jersey state law provides for closed primaries where a voter must be registered as a party member in order to participate in that party's primary. An unaffiliated voter may be able to affiliate on the day of the primary, and a voter previously affiliated with a party who wants to change their affiliation must do so by the 55th day before the primary.

* Winners in New Jersey primary elections are determined via plurality vote, meaning that the candidate with the highest number of votes wins even if they did not win more than 50 percent of votes cast.

## Background[edit]

Seal of New Jersey.

In general, there are two broad criteria by which primary elections can vary from jurisdiction to jurisdiction:

1\. Rules of participation: In jurisdictions that conduct partisan primaries, who can vote in a party's primary? Is participation limited to registered party members, or can other eligible voters (such as unaffiliated voters or voters belonging to other parties) participate? In general, there are three basic types of primary election participation models: open primaries, closed primaries, and semi-closed primaries. Several states also use a top-two primary or a variant of that system.

* In closed primaries only registered party members are allowed to vote.
* In semi-closed primaries, registered party members and unaffiliated voters are allowed to vote.
* In open primaries, all voters are allowed to vote.
* In top-two primaries, top-four primaries, and blanket primaries, all candidates are listed on the same ballot, regardless of partisan affiliation and voters may vote for candidates from more than one party.

2\. Vote requirements: What share of the total votes cast does a candidate have to receive in order to advance to the general election? Methods for determining primary election outcomes include plurality voting systems ans majority voting systems. Two states, California and Washington, use top-two primaries, while one, Alaska, uses a top-four primary. Both are plurality systems. Maine use ranked-choice voting for some primaries, which is a majority system.

## Primary election systems used in New Jersey[edit]

### Congressional and state-level elections[edit]

New Jersey state law provides for closed primaries, meaning that a voter must be registered as a party member in order to participate in that party's primary. A previously unaffiliated voter can participate in the primary of their choice by affiliating with that party at the polls on the day of the primary. Otherwise, a voter must indicate their party preference (e.g., via an updated voter registration) no later than the 55th day preceding the primary in order to vote in that party's primary. Winners in primary elections are determined via plurality vote.[1][2][3]

In 23 states, at least one political party utilizes closed primaries to nominate partisan candidates for congressional and state-level (e.g. state legislators, governors, etc.) offices. In 18 states, at least one party utilizes open primaries to nominate partisan candidates for these offices. In 12 states, at least one party utilizes semi-closed primaries. In 5 states, top-two primaries or a variation are used.[4] These state primaries are a separate entity and are not included in the totals for open, closed, or semi-closed primaries.

The table below lists New Jersey offices for which parties must conduct primary elections to nominate their candidates.

## County lines[edit]

In New Jersey, county parties have the ability to select the placement of a candidate's name on the ballot in their respective counties. The selection of the candidate can be determined by a full vote of the county party committee or at the discretion of the county party chairperson. In counties that use the process, positions up for election are listed in rows with the candidates running for those positions listed in columns. Oftentimes, the candidate endorsed by the county party will appear in the leftmost column, known as the county line, with remaining candidates appearing in columns to the right.[5]

### State court blocks county line ballot design for Democratic primaries (2024)[edit]

On February 26, 2024, three Democratic candidates for U.S. Congress sued in federal court to eliminate New Jersey's county line primary ballot design.[6] According to Politico: "The county line is New Jersey’s unique primary ballot design where party-backed candidates are placed in a single column or row from the highest office to the lowest. Candidates not endorsed by county parties are often placed less prominently on primary ballots."[7] Nineteen of New Jersey's 21 counties used the county line design at the time of the lawsuit.[7] Most jurisdictions in the United States use a ballot design that groups all candidates running for the same office in the same part of the ballot.

Among the plaintiffs in the challenge was Rep. Andy Kim (D) of New Jersey's 3rd Congressional District. At the time of the lawsuit, Kim was a candidate for the U.S. Senate seat held by Bob Menendez (D). Sarah Schoengood (D) and Carolyn Rush (D), each a candidate for a U.S. House seat in New Jersey, joined Kim in the challenge. The filing named the election clerk in all 19 counties that used the county line system as defendants.[8]

The suit alleged that the county line ballot design violated the First and 14th amendments of the U.S. Constitution, and said: "The system provides preferential ballot position for such candidates and displays them in a manner that nudges voters to select them, even when they otherwise might not."[8] A campaign spokesperson for Tammy Murphy (D), who was a candidate for U.S. Senate but later dropped out of the race, criticized the lawsuit, saying "Andy Kim doesn't have a problem with the county line system, he has a problem with the idea of losing county lines — as he is perfectly happy to participate in the process when he wins, and he has benefited from the lines in every other election he's run."[6] Defendants in the case argued that there was not enough time to modify and print ballots before the April 20 deadline to send mail ballots for the upcoming primary, and that the system helped voters identify party-supported candidates.[9]

On March 29, U.S. District Judge Zahid Quraishi issued a preliminary injunction blocking the use of the county line in the June 4th Democratic Primary.[10] In the opinion, Quraishi wrote, "Mandatory injunctive relief is reserved only for the most unusual cases. Plaintiffs’ burden on this Motion is therefore particularly heavy. Nevertheless, the Court finds, based on this record, that Plaintiffs have met their burden and that this is the rare instance when mandatory relief is warranted.”[11] In a statement released on his campaign website, Kim said of the ruling that "(t)oday's decision is a victory for a fairer, more democratic politics in New Jersey. It's a victory built from the incredible grassroots work of activists across our state who saw an undemocratic system marginalizing the voices of voters, and worked tirelessly to fix it."[12] After the decision, clerks from three counties said they would not appeal the decision.[7]

Although the ruling did not apply to the Republican primary, the New Jersey County Republican Chairs Association submitted a brief defending the constitutionality of the county line ballot design.[7]

On April 3, the U.S. Third Circuit Court of Appeals denied the remaining defendants' request to block the lower court's decision.[7] By the next day, clerks in all but two counties included in the lawsuit said they would not appeal the ruling, however the Camden County Democratic Committee (CCDC) and several other party committees continued their appeal.[9][13]

On April 15, New Jersey Vicinage 3 Superior Court Judge John E. Harrington denied a request for an injunction to block the use of county line ballots in the state's June 2024 Republican primaries. Four Republican congressional candidates brought the challenge after the March 29 ruling by Judge Quraishi that barred the use of the ballot design for state's June Democratic primaries. Judge Harrington reasoned that there was not enough time between the challenge and the scheduled primaries to grant the injunction, saying "It’s too comprehensive a change for this court do this now."[14][15]

On April 17, the Third Circuit issued a unanimous ruling upholding the lower court's decision to bar the use of the county line ballot design in the June Democratic primaries. According to reporting from the New Jersey Globe, in oral arguments "CCDC lawyer Bill Tambussi contended that the county line allows parties to exercise their constitutionally protected rights to associate with their preferred candidates and assist voters in finding those candidates."[13] In the ruling, judge Kent Jordan wrote "Nothing in the preliminary injunction prohibits the CCDC from including county parties’ slogans on the ballot, endorsing candidates, communicating those endorsements, or associating by any other constitutional means. The injunction simply means that the CCDC does not get to bracket its preferred candidates together on the ballot... Any harm to the state’s or the CCDC’s interests is outweighed by the burdens on the Plaintiffs’ associational rights.”[16]

On March 6, 2025, New Jersey Gov. Phil Murphy (D) signed A 5116 into law, abolishing the use of the county line ballot design and replacing it with a system that groups offices on the ballot into blocks of candidates and places a number next to the name of each candidate. The bill also allowed candidates running as a slate for an office with more than one open seat to appear together on the ballot. Kim, who was elected to the U.S. Senate in 2024, criticized the new bill, writing, "Almost exactly a year ago I testified in court to fix NJ’s broken ballot and make our politics more fair. The simple premise was to have every candidate treated exactly the same on the ballot. The bill signed today falls short of what voters deserve."[17][18] Democrats in the Assembly said in a statement, "The bill creates a fair ballot for all candidates, and it is in line with everything the legislature has done to protect and expand voting rights and ensure citizens’ trust our political process."[19]
