Mexico 2027 Federal Legislative Election

What this countdown tracks

The clock above counts down to Mexico's 2027 federal legislative election on Sunday, June 6, 2027 — the first nationwide vote since Claudia Sheinbaum's 2024 landslide. Voters renew all 500 seats of the Chamber of Deputies and elect 17 governors, with the Morena-led coalition's two-thirds supermajority and Sheinbaum's constitutional-reform agenda squarely on the line.

About this election

Mexico's federal Chamber of Deputies serves three-year terms, so the 2027 vote is the first chance for an electorate to react to Sheinbaum's first half-term in Los Pinos. The election is run by the National Electoral Institute (INE), itself the subject of the 2024 reform that shrank its budget and altered its governance. Concurrent gubernatorial races in 17 of the 32 states — including the State of Mexico, Veracruz, and Nuevo León — make this the largest single-day exercise in voter participation between presidential cycles.

The political backdrop is dominated by Morena's effort to lock in the constitutional changes pushed through in late 2024 and 2025: judicial overhaul, security restructuring, and the dissolution of independent regulators. The opposition PAN-PRI-PRD bloc collapsed after 2024, and the 2027 cycle will measure whether Movimiento Ciudadano or a new center-right vehicle can reorganize. Cartel violence, US-Mexico trade frictions, and the post-USMCA review window also shape the campaign.

Key issues

Expect the campaign to revolve around the security record under the Secretaría de Seguridad reorganization, the fiscal sustainability of expanded social programs, and the operational impact of the judicial reform whose first elected judges took office in 2025. Trade with the United States — including any Trump-era tariff revisions and the 2026 USMCA review — and energy policy after the Pemex bailout round are likely to dominate televised debates.

Past results

• 2024: Morena and allies won 256 seats outright in the Chamber, building a near supermajority alongside PT and PVEM.
• 2021 midterms: Morena lost its standalone majority but kept a coalition advantage; PAN, PRI, and PRD ran a joint Va por México slate.
• 2018: Morena's first federal sweep delivered AMLO the presidency and 191 deputies on its own ticket.
• 2015: PRI-led coalition retained a plurality during the Peña Nieto presidency.
• 2012: PRI returned to power after a 12-year hiatus, reshaping the chamber.
