Chapter 9: Mexico

Mexico has molded several of its institutions based on the U.S. models because it prefers presidential to parliamentary systems. Like the U.S., Mexico combines the head of state and chief of government and maintains a bicameral congress. Although it has a bicameral congress, it is not as important or valued the same as the Mexican presidency. Mexico has not yet become a true democracy because the democratic institutions within the country have been weakened by the PRI which has dominated much of Mexico’s politics, which has dominated all three branches of Mexico’s national government. When Zedillo left office, his political exit resulted in the ending of the PRI’s 71 year continuous rule but the party still maintains much control over numerous state and local governments and continued to be a major force in both chambers of the national legislature

Attached is an article that focuses on the  notorious Mexican party.
