2021 Mexican local elections

Prior to the campaigning period, 25 state governors signed an agreement with President Andrés Manuel López Obrador, which stated that they would maintain neutrality during the elections, uphold the people's free will, reject funding from organized crime, and abstain from utilizing official funds to back specific candidates or parties.^[4]

Several different criminal gangs implicated in drug trafficking, human trafficking, and fuel theft have a great deal of political influence in some states.^[5] The Sinaloa Cartel exercises considerable control in the northwest while the Jalisco New Generation Cartel′s (CJNG) influence is in the west, including the states of Michoacan and Guerrero. The Gulf Cartel and Los Zetas are powerful in the northeast.^[5]

In the past, drug cartels have influenced campaigns by supporting candidates and even running some of their own members or sympathizers as candidates for office,^[5] such as Lucero Sánchez López, former federal deputy from Sinaloa who was also Joaquín "El Chapo" Guzmán′s lover.^[6] Election-related violence is of particular concern in Michoacan, not only because of the aforementioned drug cartels but also because of armed community police who often act as vigilantes.^[6]

During the campaigning period, 91 candidates were assassinated,^[2] where 80% of the cases involved individuals who belonged to a party that did not control the state government.^[7] The secretary of Security and Civilian Protection, Rosa Icela Rodríguez, promised to step up security and provide protection to candidates who received threats.^[8]

The Instituto Nacional Electoral (INE) canceled the registration of 19 candidates of MORENA for failure to report pre-campaign expenses.^[9]

The INE canceled the registration of 49 candidates affiliated with MORENA for failing to report expenses related to their pre-electoral campaigns, which affected two gubernatorial, 25 federal deputies, six local deputies, twelve municipal presidents, and four borough president candidates. Two candidates for federal deputy and one for governor of Michoacan from the Michoacán a Redes Sociales Progresistas were also withdrawn. The party was fined MXN $6,714,893.30. Fines were also imposed on PRD (MXN $409,031), MC ($227,886), independents ($182,361), PES ($98,782), Redes Sociales Progresistas ($85,229),  PAN ($26,845), and PVEM ($1,476).^[10]

The FGR (Federal Elections Prosecutor) is investigating about 80 complaints about Internet celebrities (Spanish: influencers) who illegally used social media to sway votes toward the PVEM.^[11]

The INE said that 300 polling places could not be installed in Chiapas, Michoacán or Oaxaca due to social conditions that make voting dangerous or impossible.^[12]

Daniel Serrano, candidate ( MORENA) for municipal president in Cuautitlán Izcalli, complained about vote buying on election day.^[13] The Instituto Electoral del Estado de México (IEEM) says that irregularities and violence on election day in Nextlalpan, State of Mexico, make it impossible to give a preliminary vote count (PREP), it may be necessary to hold another election.  PRI says that vandals entered the candidate's house and burned it, in addition to sexually assaulting the candidate, and they destroyed voting material. MORENA says the allegation are false.^[14]
