By the 1840s, partisan politics was well developed, and the two major parties of the day, the Democrats and Whigs, exploited the power of song as a campaign tool. Both parties published “songsters,” pocket-sized books perfect for campaigners to attract voters with an impromptu street corner rally. The earliest songsters included only lyrics printed along with the titles of well-known tunes to which they were to be sung. Two songsters from the 1844 contest between James K. Polk (1795–1849) and Henry Clay (1777–1852) offered their followers relevant new words for old standards like “Yankee Doodle” and “Old Dan Tucker.”
