The main purpose of political debates during election cycles is to provide candidates an opportunity to present their policies, beliefs, and qualifications to the electorate. These debates facilitate an exchange of ideas, allowing voters to compare candidates on various issues such as the economy, healthcare, and foreign policy. They also serve to inform the public, fostering engagement and participation in the democratic process. Additionally, debates can significantly impact public perception and voting decisions, often being a crucial factor in determining the outcome of an election.
