A political platform serves as a formal set of principles and policies a candidate or party advocates during elections. It outlines their positions on key issues such as healthcare, education, and foreign policy, providing voters with a clear understanding of what to expect if elected. Platforms are crucial for differentiating candidates and facilitating informed voting, as they represent a party's vision for governance. They also serve as a basis for accountability, allowing voters to assess whether elected officials follow through on their stated commitments.
