Primary elections allow voters to determine which candidates compete in the general election and can be nonpartisan or partisan. In partisan primaries, voters choose the candidates they prefer for a political party to nominate in the general election.
The laws governing primary elections vary from state to state and can even vary within states by locality and political party. For example, only registered party members are allowed to vote in closed primaries, while registered party members and unaffiliated voters are allowed to vote in semi-closed primaries, and all voters are allowed to vote in open primaries.
Primary elections also vary by the way their outcomes are determined. Majority systems require the winning candidate to receive at least fifty percent of the votes cast, while plurality systems do not. In top-two primaries, top-four primaries, and blanket primaries, all candidates are listed on the same ballot, regardless of partisan affiliation.
