Summary
Closed primaries are a type of primary election where only registered members of a specific political party are allowed to vote in that party's primary. This system, which contrasts with open and semi-closed primaries, originated from the progressive movement's aim to empower the electorate in candidate nomination, though political parties retain control over the method. While supporters argue it protects party integrity and prevents sabotage, critics contend that closed primaries disenfranchise independent voters, can lead to more ideologically extreme nominees, and are problematic given their public funding. Senator Joe Manchin is a notable advocate for challenging closed primaries, believing that opening them up would benefit independent voters and potentially foster a viable third party, leading to a political shakeup before the 2028 election. Approximately 20% of U.S. states, plus D.C., utilize a strictly closed primary system.

Primary elections or primaries are elections held to determine which candidates will run in an upcoming general election. In a partisan primary, a political party selects a candidate. Depending on the state and/or party, there may be an "open primary", in which all voters are eligible to participate, or a "closed primary", in which only members of a political party can vote. Less common are nonpartisan primaries in which all candidates run regardless of party. The origins of primary elections can be traced to the progressive movement in the United States, which aimed to take the power of candidate nomination from party leaders to the people. However, political parties control the method of nomination of candidates for office in the name of the party. Other methods of selecting candidates include caucuses, internal selection by a party body such as a convention or party congress, direct nomination by the party leader, and nomination meetings. A similar procedure for selecting individual candidates under party-list proportional representation can be found in open list systems; in such systems, the party primary is combined with the general election. Parties in countries using the parliamentary system may also hold leadership elections. A party's leader will typically become the head of government should that party win a majority of seats in the legislature, meaning leadership elections often select a party's de facto candidate for prime minister, much like a presidential primary. Countries that use first-past-the-post for both the primary and general elections are often described as using a partisan two-round system to highlight the similarity to two-round (runoff) systems, particularly in two-party systems. These similarities have led to the first round of a two-round system sometimes being called a "nonpartisan primary" in the United States.
