About the Primary – Caucus – Convention System
In the summer of every presidential election year, political parties in the United States typically conduct national conventions to choose their presidential candidates. At the conventions, the presidential candidates are selected by groups of delegates from each state. After a series of speeches and demonstrations in support of each candidate, the delegates begin to vote, state-by-state, for the candidate of their choice. The first candidate to receive a preset majority number of delegate votes becomes the party’s presidential candidate. The candidate selected to run for president then selects a vice presidential candidate. Delegates to the national conventions are selected at the state level, according to rules and formulas determined by each political party’s state committee. While these rules and formulas can change from state-to-state and from year-to-year, there remain two methods by which the states choose their delegates to the national conventions: the caucus and the primary.
