Nearly half of Salvadorans believe the "maras" benefit most from the country's gang truce, according to an opinion poll, which could spell political trouble for the pact as presidential elections are looming. In a public opinion survey of 2,119 Salvadorans, El Salvador's Universidad Tecnologica found that 47 percent of respondents believed the Barrio 18 and Mara Salvatrucha (MS13) street gangs benefitted most from the truce brokered between the two groups in March 2012.
