Mexico's drug cartels appear to have declared open season on any candidate for public office who will not toe their line in the run-up to June's midterm elections. On May 14, mayoral candidate Enrique Hernández Salcedo was shot to death by gunmen who fired from a passing truck as he was making a speech in the town of Yurécuaro, Michoacán. Three spectators were injured. Hernández was a leader of the town's "self-defense force," which took up arms to break the grip of the Knights Templar drug cartel in the region. He was running with the left-opposition Morena party.

Maya indigenous peasants in Mexico's southern state of Chiapas are marching cross-country to oppose violence by the local narco gangs and the corruption of local authorities that protect them. The "pilgrimage" left the rural town of Simojovel some 15,000 strong at the end of March, and is now arriving at the state capital Tuxtla Gutiérrez, some 240 kilometers away through rugged country. The pilgrimage was organized by the Catholic pacifist group Pueblo Creyente (Faithful People) with the support of the local diocese of San Cristóbal de Las Casas in response to a wave of narco-violence in Simojovel.

Striking farmworkers in the San Quintín Valley of Mexico's Baja California blocked the main highway through the peninsula and clashed with police May 9. At least 70 protesters were injured as state police fired rubber bullets. The rioting came a day after the cancellation of a meeting between Mexican federal government officials and farmworker leaders. The farmworkers received a statement of support from the Zapatista rebels in southern Chiapas state. At the closing session of an international activist meeting in the Chiapas town of San Cristóbal de Las Casa, "Critical Thinking Against the Capitalist Hydra," the rebels' Subcommander Moises said on the day of the Baja clashes: "We have to see what we can do, compañeros and compañeras. What is happening in San Quintín enfuriates us."

March 28 saw more angry protests in Mexico's conflicted southern state of Guerrero, as students from the rural college of Ayotzinapa clashed with police in the state capital Chilpancingo at a march demanding the return alive of the 43 abducted students from the school. Cars were set on fire as police attacked the marchers. The 43 students disappeared during protests in the Guerrero town of Iguala last September, and are now believed to have been turned over a murderous narco-gang by corrupt police. The weekend before the Chilpancingo demonstration, family members of some of the 43 missing students held a vigil in New York City's Union Square—one stop on a tour of US cities to raise awareness on their plight and protest Washington's "Drug War" aid to Mexico's brutal and corrupt police forces.

Aidé Nava, 42-year-old woman running for mayor in Mexico's conflicted southern state of Guerrero, was found decapitated March 11, a day after she was abducted in her hometown of Ahuacuotzingo. The decapitated body was found in the municipality's outlying hamlet of Tecoanapa with a note signed by Los Rojos, one of the main Guerrero narco-gangs, threatening the same treatment for any politician who does not "fall in line." She had been seized the previous day by gunmen who stopped her campaign bus on a rural road. Nava's family, activists with the leftist Party of the Democratic Revolution (PRD), had long been under threat. Her husband Francisco Quiñonez Ramírez, the former mayor of Ahuacuotzingo, was gunned down by an assassin in June 2014. Their son, Francisco Quiñonez Nava, was kidnapped in October 2012 and remains missing.

Mexican authorities on March 4 announced the capture of Omar Treviño AKA "Z-42"—leader of Los Zetas, the ultra-violent narco-paramilitary network that has long terrorized the country. Z-42 was detained without a shot being fired by federal police and soldiers in San Pedro Garza García, an upscale suburb of northern industrial hub Monterrey, officials said. US DEA chief Michele Leonhart congratulated Mexico, saying the bust "strikes at the heart of the leadership structure of the Zetas." The US State Department had a $5 million price on Treviño's head, while Mexican authorities offered $2 million.

Mexican authorities on Feb. 27 announced the capture of the country's most-wanted drug lord, Servando Gómez AKA "La Tuta"—boss of Michoacán's feared Knights Templar cartel. After a long surveillance operation, "La Tuta" was taken without a shot in a raid on a house in state capital Morelia. Also known as "El Profe" due his past as a schoolteacher, the leader of the cultish Knights Templar had overseen a bloody campaign for control of the Michoacán plaza (sphere of operations) against the group's principal rival, La Familia Michoacana, from which it broke off in 2010. Despite a $2 million price on his head, La Tuta had publicly proclaimed that he would rather die than go to prison. After his capture, he was taken to Mexico City, where he was paraded before TV cameras, before being flown by helicopter to the maximum-security Altiplano prison. Police seized several Michoacán properties in the weeks leading up the capture and arrested several of his associates, including his brother, Flavio Gómez, who was said to be in charge of the cartel's finances. The Knights Templars are said to control sprawling agricultural lands and real estate across Michoacán.

Yet more grim evidence emerged this week that Mexico's warring cartels are becoming a real military force and underground parallel state in the country's lawless northeast. Small Wars Journal on Feb. 13 noted a press release from the Mexican attorney general's office, the PGR, announcing that federal police and army troops had raided a winery near Nuevo Laredo, Tamaulipas state, where 13 vehicles were being fitted with armor plating. Small Wars Journal calls it a "narco-tank factory." A huge amount of ammunition was also confiscated in the raid, although it seems the people who were running the workshop all escaped. The PGR said they believe the makeshift factory was being run by the Gulf Cartel.
