Bases of Support for Mexico's Dominant Party

Abstract

The purpose of this paper is to elucidate the bases of support for Mexico's Partido Revolucionário Institucional . A model is developed which identifies the major and minor variables affecting changes in PRI support in the six elections between 1952 and 1967. Throughout the paper the unit of analysis is the state; the dependent variables are voter turnout and the percentage of the total vote in each state received by the PRI .
