In a closed primary, only voters registered for the party which is holding the primary may vote. For example, if the Republican Party is holding a closed primary, then only voters registered as Republicans are permitted to vote in the primary.[2]
In some states, parties may have the option to invite unaffiliated voters to participate in a closed primary. Generally, unaffiliated voters will not be permitted to participate in a closed primary unless they choose to give up their unaffiliated status.[3]
| Nominees for elected offices at all levels are chosen by party organizations in a variety of ways, including primary elections, caucuses, and conventions. The precise method of choosing nominees can vary significantly between states, and even within states for different offices. For example, nominees for state-level offices may be selected at primaries or conventions, while presidential nominees may be chosen by delegates selected at primaries or caucuses. |

Arguments for and against
Proponents of closed primaries argue that they preserve a political party's freedom of association and prevent members of other parties from "crossing over" to influence the nomination of an opposing party's candidate.[3][17]
Critics of the closed primary system argue that it exacerbates radicalization, as candidates must cater to a party's base, which is sometime more extreme, rather than the political center. Voters who participate in primaries are often dedicated party regulars to whom candidates must appeal to win the primary. Once emerging from the primary, candidates often must change the focus of their campaigns to appeal to a broader electorate.[3][2]
Critics also argue that because the closed primary often excludes unaffiliated voters, they are disenfranchised from choosing a possible nominee.[2]
