To declare support for a popular movement or trend with the intention of profiting or reaping some sort of easy material gain, usually without believing in the movement or trend. The expression is believed to have originated in the Southern States of America, probably dating from the first presidential campaign of William Jennings Bryan (1860-1925) in 1892, when candidates for political elections would parade through the streets led by a band of musicians performing on a large horse–drawn dray. As a publicity stunt the local candidate would mount the wagon as it passed and ride through his constituency with the band as they played, in an attempt to gain personal support from the voters. Bryan never won the presidency, losing to McKinley in 1896 and 1900. and to Taft in 1908. He was, however, appointed Secretary of State in 1913, but resigned from the government in 1915, believing that President Wilson’s policies would bring the United States into the First World War, a bandwagon he did not wish to climb on.
