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. As of February 2026, both the Democratic Party and the Republican Party were scheduled to hold closed primaries in 2026 and 2027, in which only registered party members could participate.^[1]^[2]^[3]
