The purpose of primaries and caucuses is to determine party delegate votes, which ultimately play a role in electing the president and selecting the members of Congress. They help determine the level of support candidates have within their party and shape the nomination process for each political party. The delegates elected through these processes ultimately vote on behalf of their party at the national conventions, where the final candidate for president is decided. These primaries and caucuses also indirectly influence Electoral College votes, as the winning candidate in each state typically receives the electoral votes for that state.
