The victory by Vicente Fox Quesada in Mexico's July 2000 presidential election was a watershed in the country's political history. His triumph convincingly marked the consolidation of electoral democracy and, by ending seven decades of uninterrupted national rule by the "official" Institutional Revolutionary Party (PRI), symbolized a clear break with the political regime established following the 1910-1920 revolution. Nevertheless, many legacies of postrevolutionary authoritarianism persist, and Mexico's democratization process remains incomplete. The seventeen contributors to this volume assess Mexico's political dynamics at the turn of the century and the many pending challenges in the construction of a more fully democratic political order. They examine: (1) changes affecting the party system, electoral institutions, and voting behavior; (2) the evolving role of the armed forces, organized labor, big business, and rural producers; (3) the new importance of civil society, the mass media, and cross-border social coalitions; (4) and key issues of political representation and governance, including executive-legislative relations, judicial performance, federalism, the constitutional rights of indigenous peoples, and the political role of Mexicans resident in the United States.
