This paper explores the formation of a political order, a constituency, during the 1938-1940 senatorial campaign of the "Partido Popular Democratico" in Puerto Rico. In particular it examines the constitutive force of the "Catecismo del Pueblo," a small booklet in the form of questions and answers regarding the party's basic assumptions and orientations. This booklet developed a political constituency by mediating a covenantal relationship through discourse in the form of a catechism. Burke's notion of constitutional dialectics is used to explore the Catecismo's nature as constitutive, as a catechism, and as the mediator of a political covenant between the Party and the "jibaros."
