The main function of a political party in an electoral system is to aggregate interests and facilitate the governance process by organizing candidates for election. Political parties serve as platforms for advocating specific policies and ideologies while mobilizing voters to participate in elections. They also help articulate diverse public interests, simplifying complex political preferences into coherent platforms that appeal to a broader electorate. Additionally, parties provide structures for political participation, foster civic engagement, and offer voters choices in representatives, thereby contributing to the overall functioning of the democratic process.
