The Mexican political system is a federal republic, meaning it has a division of powers between the national government and individual states. It consists of three branches: the executive, led by the President, the legislative, which includes a bicameral Congress, and the judicial branch. The President is elected for a six-year term and cannot serve consecutive terms. The legislative branch is divided into two chambers: the Senate and the Chamber of Deputies. Senators serve for six years, while Deputies serve for three years. Elections are held every three years, allowing citizens to vote for their representatives at both the national and local levels.
