Campaign songs are songs used by candidates or political campaigns. Most modern campaign songs are upbeat popular songs or original compositions that articulate a positive message about a campaign or candidate, usually appealing to patriotism, optimism, or a good-natured reference to a personal quality of the candidate such as their ethnic origin or the part of the country they are from. In some cases, the campaign song can be a veiled attack on an opposing candidate or party. The use of a campaign song is primarily known in the quadrennial United States presidential election, where both major party candidates usually use one or more songs to identify with their campaign.
