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. The documents are in the form of computer files given the paper by someone who formerly worked with Televisa.

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 marchers also rejected the candidate of the center-right National Action Party (PAN), Josefina Vázquez Mota, who shares second place in most polls with center-left candidate Andrés Manuel López Obrador.

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.

On May 19, the Mexican army announced the arrest of eight suspects in the massacre of 49 people who were decapitated, mutilated and left in plastic bags on the side of a highway in Cadereyta, Nuevo León, just outside Monterrey last week. Among those arrested was suspected ringleader Daniel Elizondo, AKA "El Loco"—said to be a member of the Gulf Cartel. Drugs, guns and hand grenades were seized during the arrests. However, authorities earlier said that the graffito "100% Zeta" found near the bodies indicated that Los Zetas, the Gulf Cartel's bitter rivals, were responsible. At the time of the massacre, local authorities resorted to the now common tactic of playing down its significance. "This continues to be violence between criminal groups," said Jorge Domene, Nuevo Leon's state security spokesman. "This is not an attack against the civilian population." Yet authorities admitted the victims had not been identified, and may have been migrants attempting to cross into the United States. (AlJazeera, May 20; AP, May 19; AP, May 15; CNN, May 14)

The week of actions was initiated by the New York-based Movement for Justice in El Barrio.

Left-leaning independent unions dominated celebrations of International Workers Day in Mexico on May 1, while some centrist labor federations decided not to hold marches, reportedly because of concern over security. Tens of thousands of unionists, campesinos and other activists participated in the independent unions' annual march to Mexico City's main plaza, the Zócalo; the left-leaning daily La Jornada reported that more unions and more unionists took part than in previous years.
