In the United States, political parties nominate their presidential candidates through the use of precinct, county and state-level primary elections or caucuses. Primaries and caucuses help delegates come to a consensus on who should be the party nomination for the presidential election. At the end of primaries and caucuses, the political parties formally announce their nominees for the presidency at the national conventions.

History of the Systems

After the American Revolution, the legislative caucus system emerged as a way for voters to make political nominations for state offices in addition to the congressional caucus system for presidential nominations. Before the 1820s, caucuses were held in private by party leaders. This practice was challenged by President Andrew Jackson and other reformers who believed that the lack of public participation made the process less democratic. Therefore, the conventional caucus system, where voters picked delegates who would ultimately choose the final candidate, replaced legislative and congressional systems. However, in the early 20th century, the primary system began to emerge. The primary system allowed voters to elect party officials themselves, instead of party delegates. Today, both direct primaries and caucuses are used, depending on the state.

Primary System

In the primary system, voters choose the candidate they support on a secret ballot. There are two types of primaries in electing a nominee: closed and open. Closed primaries only allow individuals to vote in a Democratic or Republican primary if they are registered members of the party. For those who are registered as an unaffiliated voter, they will receive a ballot on measures and nonpartisan contests, without the ability to vote on a party nominee. In contrast, an open primary allows all registered voters to vote in the primary, regardless of their party affiliation.

Caucus System

Unlike the primary system, the caucus system is a public affair for party voters and leaders. Caucuses are held according to precinct, county or district. At a caucus, participants congregate in groups and publicly declare their vote for delegates. Depending on state rules for caucuses, these delegates will later go on to the county or state convention before voting in the party national convention. Participants can also sway undecided voters to their group or switch camps before the final tally. The group with the most supporters wins delegate votes and the delegate pledge to vote for a particular candidate in the national convention. Today, the only states that use the caucus system purely are Maine, Colorado, Alaska, Nevada, Hawaii, Kansas, Wyoming, Minnesota, North Dakota and Iowa.

Significance of Primaries and Caucuses

Primaries and caucuses play an important role in determining which candidates will be chosen for running in the general election. States that vote through primaries give more voters a chance to pick a candidate efficiently through the ballot system, and the percentage of voters who participate in a primary are higher than those who participate in a caucus. On the other hand, caucuses give more active voters a chance to meet and congregate with others, immersing themselves in an hours-long process. Some states, such as Texas, even use a mix of both caucuses and primaries to give voters a choice in how they would like to participate. While the caucus and primary systems differ, they both are examples of the democratic process in the United States.
