Cárdenas had pushed for women's suffrage in Mexico, responding to the pressure from women activists and from the political climate that emphasized equality of citizens. Mexico was not alone in Latin America in not enfranchising women, but in 1932, both Brazil and Uruguay had extended suffrage to women, and Ecuador had also done so. Women had made a significant contribution to the Mexican Revolution, but had not made gains in the postrevolutionary phase. Women who were members of the National Peasants Confederation ("Confederación Nacional Campesina") or the Confederation of Mexican Workers ("Confederación de Trabajadores Mexicanos") were, by virtue of their membership umbrella organizations, also members of Cárdenas's reorganized party, the Party of the Mexican Revolution or PRM, done in 1938. In practice, however, women were marginalized from power. Women could not stand for national or local governmental elections or vote. The Constitution of 1917 did not explicitly address women's rights and so to enfranchise women required a constitutional amendment. The amendment itself was simple and brief, specifying that "mexicanos" referred to both women and men.
