Oaxaca, from 2024 to 2027

All ten of Oaxaca's federal districts are classified by the INE as Indigenous; only Yucatán shares that feature across all of its districts. In 2024 all ten went to Morena, alone or in coalition: Sigamos Haciendo Historia won seven, and in the three where the allies did not field a joint candidate, Tlacolula de Matamoros (4), Salina Cruz (5) and Miahuatlán (10), Morena won on its own. In those three, the runner-up was not Fuerza y Corazón por México but one of Morena's usual partners: the PT in Tlacolula and Miahuatlán, the Greens in Salina Cruz.

Oaxaca was also where the PT posted its highest share, 12.5% of the valid vote, while the Greens gathered 12.0%, so with Morena's 50.9% the three added up to 75.4%, behind only Tabasco and Chiapas among the 32 states. The PRI got 8.7%, ahead of Movimiento Ciudadano (8.1%), and the PAN just 4.7%, one of its three lowest results. The widest margin came in Tlaxiaco (6), at 69.1 points. Turnout, at 60.0%, was half a point below the national rate, and 5.3% of ballots were spoiled.

Oaxaca's governorship is not on the 2027 ballot, but it does renew all 42 seats of its congress, including the migrant seat, and 152 municipal councils chosen through political parties; the rest of its municipalities choose their authorities under Indigenous normative systems, outside that ballot. The federal deputy ballot will no longer include the PRD, and it will be the first for SOMOS and PAZ.
