Tens of thousands marched through the center of Mexico City on June 10 in a festive protest against former México state governor Enrique Peña Nieto, the frontrunner in the July 1 presidential election, and against the television networks that the demonstrators said were promoting his candidacy. The march was the latest in a series of protests since a new student movement widely known as "#YoSoy132" ("I'm number 132") appeared suddenly in May in opposition to Peña Nieto and the likely return of his centrist Institutional Revolutionary Party (PRI) to power; the PRI dominated Mexican politics for 71 years until losing the presidency in 2000. The capital's police estimated the crowd at 90,000 on June 10, about twice the police estimate for a similar march on May 19. (La Jornada, Mexico, June 11)

Backed up by Mexican soldiers, state homicide detectives arrested the municipal police chief and six other police agents in Lagos de Moreno in the western state of Jalisco on June 6 for allegedly participating in the kidnapping of three men five months earlier. The victims—attorney César Raúl Alcalá Gaona; his assistant, Jorge Alejandro Arredondo Siller; and construction worker Jorge Alberto Bustos Nájera, all from Saltillo, Coahuila—were found dead from asphyxiation and beating a few hours after they were kidnapped. The police agents are believed to have been working for Jalisco New Generation, a drug gang.

In a wee-hours raid on June 12, heavily armed FBI and Border Patrol agents in 15 vehicles swept into the Ruidoso Downs Racetrack and Casino, in Ruidoso, NM, seizing dozens of racehorses. A simultaneous raid was carried out at Zule Farms, in Lexington, Okla, which apparently supplied horses to the Ruidoso track. A total of seven were arrested in the raids, accused of using the horse trade to launder money for Los Zetas drug cartel. Indicted in the case are accused Zeta commanders Miguel Angel Treviño Morales AKA "Z-40" and his brother Oscar Omar Treviño Morales AKA "Z-42"—who are presumed to remain at large in Mexico.

In an article dated June 7, the British daily The Guardian said it had received documents apparently showing that Mexico's largest television network, Televisa, was paid in 2005 to have its news and entertainment programs influence voters' perceptions of various politicians.

Former México state governor Enrique Peña Nieto is still favored to win Mexico's July 1 presidential elections, but polls released at the end of May showed his lead over the other candidates slipping. After being considered the certain winner for months, Peña Nieto, the candidate of the centrist Institutional Revolutionary Party (PRI), was only four percentage points ahead of former Mexico City mayor Andrés Manuel López Obrador in a poll published by the conservative daily Reforma on May 31. Peña Nieto led voter intentions with 38%, according to Reforma, down from 45% in March; López Obrador, who is running with a center-left coalition, followed closely with 34%, up from 22% in March; and Josefina Vázquez Mota, the candidate of the governing center-right National Action Party (PAN), came in third with 23%, down from 32% in March.

Private and public university students sponsored a massive march in Mexico City on May 19 to protest media coverage of the July 1 presidential and legislative elections and the widely expected victory of former México state governor Enrique Peña Nieto, the presidential candidate of the centrist Institutional Revolutionary Party (PRI).

The body of Mexican journalist Marco Antonio Avila, kidnapped three days earlier in Ciudad Obregón, Sonora state, was found May 19 along a beachside highway near Guaymas, in a plastic bag, with signs of torture and a threatening "narco-message." He had written for the Ciudad Obregón newspapers Diario Sonora de la Tarde and El Regional de Sonora. It was but the most recent in a wave of attacks on the press in Mexico. One week earlier, the office of El Mañana in Nuevo Laredo, Tamaulipas, was sprayed with bullets. Days before that, three freelance crime-beat photographers were assassinated in Veracruz. In late April, Regina Martínez, a reporter for the national weekly Proceso, was found dead with signs of torture in her home in Xalapa, also in Veracruz state.
