MEXICO'S NATIONAL, MID-TERM ELECTlONS OF JULY 1997 PRODUCED important changes in the country's political landscape. The ruling Institutional Revolutionary Party (PRI), which has dominated virtually all realms of Mexican politics since the late 1920s, suffered an unprecedented setback, losing its majority in the lower house of the Mexican Congress.
Though the era of single-party political domination appears to have come to an end, policy-making since the July 1997 elections has exhibited considerable continuity. Notwithstanding the opposition's new legislative majority, the will of the President, Ernest0 Zedillo, of the PRI, has prevailed on important issues of public policy. What can the continued legislative strength of the President, in the wake of significant opposition gains, tell us about the nature of democratization in Mexico?
