Each of the 50 U.S. states, the District of Columbia, and five territories of the United States hold either primary elections or caucuses to help nominate individual candidates for president of the United States. This process is designed to choose the candidates that will represent their political parties in the general election.
The United States Constitution has never specified this process; political parties have developed their own procedures over time. Some states hold only primary elections, some hold only caucuses, and others use a combination of both. These primaries and caucuses are staggered, generally beginning sometime in January or February, and ending about mid-June before the general election in November. State and local governments run the primary elections, while caucuses are private events that are directly run by the political parties themselves. A state's primary election or caucus is usually an indirect election: instead of voters directly selecting a particular person running for president, they determine the number of delegates a candidate will receive from their respective state for each party's national convention. These delegates then in turn select their party's presidential nominee. The first state in the United States to hold its presidential primary was North Dakota in 1912, following on Oregon's successful implementation of its system in 1910.
Each party determines how many delegates it allocates to each state. Along with those "pledged" delegates chosen during the primaries and caucuses, state delegations to both the Democratic and Republican conventions also include "unpledged" delegates who have a vote. For Republicans, they consist of the three top party officials who serve At Large from each state and territory. Democrats have a more expansive group of unpledged delegates called "superdelegates", who are party leaders and elected officials. If no single candidate has secured an absolute majority of delegates (including both pledged and unpledged), then a "brokered convention" occurs: all pledged delegates are "released" after the first round of voting and are able to switch their allegiance to a different candidate, and then additional rounds take place until there is a winner with an absolute majority.
The staggered nature of the presidential primary season allows candidates to concentrate their resources in each area of the country one at a time instead of campaigning in every state simultaneously. In some of the less populous states, this allows campaigning to take place on a much more personal scale. However, the overall results of the primary season may not be representative of the U.S. electorate as a whole: voters in Iowa, New Hampshire and other less populous states which traditionally hold their primaries and caucuses in late-January/February usually have a major impact on the races, while voters in California and other large states which traditionally hold their primaries in June generally end up having a significantly reduced say because the races are usually over by then. As a result, more states vie for earlier primaries, known as "front-loading", to claim a greater influence in the process. The national parties have used penalties and awarded bonus delegates in efforts to stagger the system over broadly a 90-day window. Where state legislatures set the primary or caucus date, sometimes the out-party in that state has endured penalties in the number of delegates it can send to the national convention.
History Background
There is no provision for the role of political parties in the United States Constitution, since the Founding Fathers did not originally intend for American politics to be partisan. In Federalist Papers No. 9 and No. 10, Alexander Hamilton and James Madison, respectively, wrote specifically about the dangers of domestic political factions. Thus in the first two presidential elections, the Electoral College handled the nominations and elections in 1789 and 1792 that selected George Washington. The beginnings of the American two-party system then emerged from Washington's immediate circle of advisors. Hamilton and Madison, who wrote the aforementioned Federalist Papers against political factions, ended up being the core leaders in this partisanship: Hamilton became the leader of Federalist Party while Madison co-helmed the Democratic-Republican Party with Thomas Jefferson.Richard Hofstadter, The Idea of a Party System: The Rise of Legitimate Opposition in the United States, 1780–1840 (1970)Gordon S. Wood, Empire of Liberty: A History of the Early Republic, 1789–1815 (Oxford History of the United States)
Congressional caucus era (17961832) Starting with the 1796 election, congressional party or a state legislature party caucus selected the party's presidential candidates. Before 1820, Democratic-Republican members of Congress would nominate a single candidate from their party. That system collapsed in 1824, and since 1832 the preferred mechanism for nomination has been a national convention.James S. Chase; Emergence of the Presidential Nominating Convention, 1789–1832 (1973)
Caucus and convention era (18321912) The first national convention to nominate a presidential candidate was called by the Anti-Masonic Party in 1831, as they could not use the caucus system because they had no congressmen. The party leaders instead called for a national meeting of supporters to set the party's candidate. This convention was held in Baltimore, Maryland, on September 26, 1831, which selected William Wirt as their presidential candidate.
Delegates to the national convention were usually selected at state conventions whose own delegates were chosen by district conventions. Sometimes they were dominated by intrigue between political bosses who controlled delegates; the national convention was far from democratic or transparent.
Mixed primary and caucus era (191268) Progressive Era reformers looked to the primary election as a way to measure popular opinion of candidates, as opposed to the opinion of the bosses. Florida enacted the first presidential primary in 1901. The Wisconsin direct open primary of 1905 was the first to eliminate the caucus and mandate direct selection of national convention delegates. In 1910, Oregon became the first state to establish a presidential preference primary, which requires delegates to the National Convention to support the winner of the primary at the convention. By 1912, twelve states either selected delegates in primaries, used a preferential primary, or both. By 1920 there were 20 states with primaries, but some went back, and from 1936 to 1968, 12 states used them.
The primary received its first major test in the 1912 election pitting incumbent president William Howard Taft against challengers Theodore Roosevelt and Robert La Follette. Roosevelt proved the most popular candidate, but as most primaries were non-binding "preference" shows and held in only fourteen of the-then forty-eight states, the Republican nomination went to Taft, who controlled the convention.
Seeking to boost voter turnout, New Hampshire simplified its ballot access laws in 1949. In the ensuing non-binding "beauty contest" of 1952, Republican Dwight Eisenhower demonstrated his broad voter appeal by out-polling the favored Robert A. Taft, "Mr. Republican." Also, Democrat Estes Kefauver defeated incumbent president Harry S. Truman, leading the latter to decide not to run for another term.Paul T. David. Presidential Nominating Politics in 1952. (1954) Volume: 1: pp 37–40. The first-in-the-nation New Hampshire primary has since become a widely observed test of candidates' viability.
National binding primary era (1972present) The impetus for national adoption of the binding primary election was the chaotic 1968 Democratic National Convention. Vice President Hubert Humphrey secured the presidential nomination despite not winning a single primary under his own name. After this, a Democratic National Committee-commissioned panel led by Senator George McGovern – the McGovern–Fraser Commission – recommended that states adopt new rules to assure wider participation. A large number of states, faced with the need to conform to more detailed rules for the selection of national delegates, chose a presidential primary as an easier way to come into compliance with the new national Democratic Party rules. The result was that many more future delegates would be selected by a state presidential primary. The Republicans also adopted many more state presidential primaries. By 1992, Democrats had primaries in 40 states and Republicans in 39.
Procedure Both major political parties of the U.S.—the Democratic Party and the Republican Party—officially nominate their candidate for president at their respective national conventions. Each of these conventions is attended by a number of delegates selected in accordance with the given party's bylaws. The results of the presidential primaries and caucuses bind many of these delegates, known as pledged delegates, to vote for a particular candidate.
Both parties also have a group of unpledged delegates. Republicans have three At-Large delegates selected at the state convention from all the states and territories, 168 in number. These are each states' two national committeepersons and the state chairperson.
In Democratic primaries through 2016, about 85% of delegates to the Democratic National Convention are "pledged delegates" who are apportioned to candidates according to the results of primaries and caucuses. The remaining 15% are unpledged superdelegates (consisting of sitting Democratic governors, sitting Democratic members of Congress [i.e., senators and representatives], former and current Democratic presidents and vice presidents, and a few leaders of Democratic National Committee-affiliated organizations, such as the Young Democrats of America) who can vote for whomever they wish.Jeff Naft, The Reason Why Dozens of Lobbyists Will Be Democratic Presidential Delegates , ABC News (February 29, 2016).Becca Stanek, Superdelegates, explained , The Week (April 4, 2016). Some superdelegates are former or current state or federal lobbyists.

Types of primaries and caucuses
Franchise in a primary or caucus is governed by rules established by the state party, although the states may impose other regulations.
While most states hold primary elections, a handful of states hold caucuses. Instead of going to a polling place, voters attend local private events run by the political parties, and cast their selections there. One disadvantage of caucuses is that the state party runs the process directly instead of having the state and local governments run them. Another is that most election laws do not normally apply to caucuses.
