In a closed primary, only party members select a political party's nominee for office.

Explanation:

A closed primary election refers to an internal election to a political party or organization, which restricts the set of candidates to a future election, based on electoral projects or programs elaborated by themselves, which is decided only by the members of the party. On the opposite, open primaries allow every citizen to vote, even if they are not registered in the party.

Both the Democratic Party and the Republican Party of the United States of America use primary elections to select the respective candidates for the presidential election. In every state, there are differences regarding primary elections: for example, Alabama holds open primary elections, while those in New York are closed.
