IV. Politics--Musical/Rhythmic Intelligence. One of the most effective instruments at the disposal of politicians has always been the campaign song. The Populists, perhaps more than any other political party or movement in the late nineteenth century, were prolific songwriters. The Populists were often quite critical of monopolies, railroads, and old party bosses in their songs. The 1890s campaign song My Party Led Me, by S. T. Johnson, provided voters with a rationale for leaving their old political party and joining the Populist cause.
