# 2021 Mexican local elections

The 2021 Mexican local elections, held on June 6, 2021, saw voters electing fifteen governors for six-year terms, deputies for thirty state congresses, and officials for 1,910 municipalities. These elections took place concurrently with the country's federal legislative election. The elections, alongside the federal legislative election, were one of the most violent in the country's history, with 91 candidates assassinated prior to election day.
In the lead-up to the election, two prominent electoral alliances were formed: the ruling coaltiton Juntos Hacemos Historia, a left-wing coalition consisting of MORENA, the Labor Party and the Ecologist Green Party of Mexico, and Va por México, a big-tent featuring the National Action Party, the Institutional Revolutionary Party and the Party of the Democratic Revolution. Additionally, Citizens' Movement participated in the elections as an independent party. 13 of the 15 gubernatorial seats up for election were being defended by a party in Va por México.
In the gubernatorial elections, Juntos Hacemos Historia achieved remarkable success, securing twelve out of the fifteen governorships, flipping eleven, while Va por México was only able to successfully defend two of their thirteen seats. The Institutional Revolutionary Party suffered the biggest loss, losing all of its seats up for election to Juntos Haremos Historia, marking the end of the party's state level dominance in Mexican politics.

## Background

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.

### Influence of organized crime

Several different criminal gangs implicated in drug trafficking, human trafficking, and fuel theft have a great deal of political influence in some states. 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.
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, such as Lucero Sánchez López, former federal deputy from Sinaloa who was also Joaquín "El Chapo" Guzmán′s lover. 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.

## Incidents
### Political assassinations

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

### Irregularities and fines

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

### Election day violence

Daniel Serrano, candidate (MORENA) for municipal president in Cuautitlán Izcalli, complained about vote buying on election day. 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.
Violence was reported in Amecameca, Metepec, Naucalpan, Nextlalpan, and Valle de Chalco.
