The main functions of a political party's platform include outlining the party's core principles and positions on key issues. The platform serves as a guide for candidates running for office, providing voters with a comprehensive understanding of the party's vision and policy priorities. Additionally, the platform helps unify members by establishing common goals and fostering a sense of identity within the party. During election campaigns, party platforms influence voter perceptions and can serve as a tool for comparing and contrasting different parties' stances on important matters.
