Political parties are the backbone of American democracy, shaping policy and representing diverse ideologies. These organized groups aim to win elections, implement their agendas, and serve as a bridge between government and citizens, simplifying complex issues for voters. The US two-party system, dominated by Democrats and Republicans, has evolved since the nation's founding. While third parties occasionally emerge, they rarely achieve long-term success. Parties recruit candidates, mobilize voters, raise funds, and facilitate peaceful power transfers in the democratic process.
