Political parties select their candidates for elections through a process that often includes primaries and caucuses. In the U.S., voters participate in primaries, where party members choose their preferred candidates for the general election. Some parties use the caucus system, which involves gatherings of party members to discuss and endorse candidates. Party conventions finalize nominations, showcasing party unity. The selection process varies between parties but generally aims to identify candidates who resonate with the party’s ideology and can appeal to a broader electorate.
