Primaries are elections held by political parties to select their candidates for the general election. These elections can be open, allowing any registered voter to participate, or closed, where only registered party members can vote. The results determine which candidates will represent the party in the upcoming election. In the United States, primaries are crucial for the Democratic Party and Republican Party as they shape the political landscape. Candidates campaign to gain support from party members, and the process often includes debates and rallies. The primary season typically occurs several months before the general election, influencing voter choices nationwide.
