The Democratic National Convention (DNC) is a gathering held every four years by the Democratic Party in the United States. Its primary purpose is to nominate the party's candidate for the presidency and to establish the party platform, which outlines its policies and goals. Delegates from each state participate in the convention, where they vote to select the nominee. The DNC also serves as a platform for party leaders, elected officials, and activists to rally support and energize voters ahead of the general election. The event typically features speeches, discussions, and various activities aimed at promoting the party's vision and values.
