Party committees are groups within political parties that focus on specific tasks, such as organizing campaigns, fundraising, and developing party policies. These committees play a crucial role in supporting candidates during elections and ensuring the party's platform is effectively communicated to voters. Each major political party, like the Democratic Party and the Republican Party, has its own set of committees, including the National Committee and various state and local committees. These committees work together to coordinate efforts and resources, helping to strengthen the party's presence and influence in the political landscape.
