A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. Arizona utilizes a semi-closed primary system. Unaffiliated voters may choose which party's primary they will vote in, but voters registered with a party can only vote in that party's primary.^[1]^[2]^[3]
