Mexico is one of the most testable countries in AP Comparative Government because it answers a big question: how can a country have a constitution, elections, and a legislature—yet function for decades like a one-party system?

In this video, you’ll learn:

• The key AP Comp Gov concepts to use in Mexico: legitimacy, institutions, participation, rule of law, accountability, and democratization

• Mexico’s big political story: PRI dominance → growing opposition → more competitive democracy

• Mexico’s system basics: a federal presidential system and why the executive has historically been strong

• How Congress works (including the idea of a bicameral legislature) and how checks grow as competition grows

• How electoral reforms can increase trust and change political outcomes

• Why parties matter in a parliamentary vs presidential comparison—and how parties reflect political cleavages in Mexico

• How civil society and movements (including the Zapatista movement in Chiapas) connect to participation and legitimacy

• Why rule of law challenges (corruption and enforcement gaps) matter for stability and legitimacy
