Political debate is a public discussion among candidates or representatives of a political party on their policies and qualifications for office. It is a key component of democracy in that it enables voters to compare and contrast views and ideas, while also influencing voter perceptions and choices. Debates are a vital part of the election process and have been shown to be effective for civic education. A debate’s effectiveness is highly subjective but some important elements include: candidate participation, active moderation posing questions on various topics of interest to voters, clear and consistent rules offering equal time for participation, and availability of the broadcast for its outreach to prospective voters.
In addition, debates offer an opportunity for voters to engage in a more meaningful and substantive way than paid media and individual voter engagement experiences such as door-to-door canvassing or a five-minute conversation with an unpaid college intern on the campaign trail. This allows voters to see the whole picture, which is sometimes impossible through a 30-second television advertisement or a five-minute conversation between two people on social media.
The origin of the modern presidential debate can be traced back to the Lincoln-Douglas Senate campaigns in 1858. This was the first significant political debate that provided an opportunity for voters to interact with and learn about competing views of the issues they faced in deciding who to support for a seat or president. Television transformed the debate, as did the advent of public opinion polling and the rise of political pundits who could shape a candidate’s message for a national audience.
