result nationally (i.e., to win 50% of the legislative seats, a party must win at least 42% of the vote nationwide). There are three exceptions on this rule: first, a party can only lose PR-seats due to this rule (and no plurality-seats); second, a party can never get more than 300 seats overall (even if it has more than 52% of the vote nationally); and third, a party can exceed this 8% rule if it wins the seats in the single-member districts. Deputies may serve up to four consecutive terms. Chamber of Senators The Chamber of Senators (Cámara de Senadores) has 128 members, elected for a six-year term. 96 of these seats are in three-seat constituencies (corresponding to the nation's 31 states and Mexico City, the former Federal District which is the national capital). In these constituencies, two seats are awarded to the party with the most votes and one seat is awarded to the party with the second most votes. The remaining 32 seats are awarded by proportional representation on a nationwide basis. Senators may run for a consecutive term. Eligibility Candidates for the Chamber of Senators must be registered voters at least 25 years old. They also must have been born in, or been residents of the states they are running in for at least six months. Electoral magistrates, the Secretary of the Electoral Tribunal, and the Executive Secretary and Executive Director of the INE must separate themselves from their positions for at least three years before seeking legislative office. State and municipal level At the local level, each of Mexico's 31 constituent states elects a governor to serve a six-year term; they also elect legislative deputies who sit in state congresses, and municipal presidents (presidentes municipales, or mayors). Mexico City, the national capital, elects a head of government in lieu of a mayor, city assemblymen in lieu of state congressional deputies, and borough mayors in lieu of municipal mayors.
