How are Mexican senators elected?

How are Mexican senators elected?

• A. 128 senators: 96 elected at the state level (2 by plurality in each state and 1 by the party with the second-highest vote in the state) and 32 elected by nationwide proportional representation.
• B. 128 senators all elected by nationwide proportional representation.
• C. 64 senators elected at the state level.
• D. The President appoints all senators.

Answer: (C)

Mexican senators are elected through a mixed system that combines state-level voting with nationwide proportional representation. There are 128 seats in total. In each state, two senators are chosen by plurality, meaning the leading candidates win seats based on the state vote. Across all 32 states, this state-level process yields 64 senators elected directly. The remaining 64 seats are filled through nationwide proportional representation, allocated to parties based on the national vote to reflect overall party support. So, describing the state-level portion as 64 senators correctly captures how a substantial part of the chamber is elected, while the other half comes from proportional representation at the national level. The other options misstate the balance or the method, which is why they’re not accurate.
