The United States will hold primary elections in 2026, serving as the initial stage in the presidential nomination process. These primaries allow voters to express their preference for a candidate within a particular political party. The exact rules and procedures governing these elections differ significantly from state to state, as well as between the Democratic and Republican parties. Variations exist in how delegates are awarded and whether the primaries are "open" – allowing any registered voter to participate – or "closed" – restricting participation to registered party members. Understanding these nuances is crucial for comprehending the overall electoral landscape. Ultimately, the primary elections help narrow the field of candidates before the national conventions. They play a vital role in shaping the eventual nominees who will compete in the general election.
