Andres Manuel Lopez Obrador (C), presidential candidate for the Party of the Democratic Revolution (PRD), leaves his campaign headquarters after attending a news conference in Mexico City July 3, 2012. Mexico's presidential election runner-up, leftist Lopez Obrador, said on Tuesday he would ask the country's election authorities to recount the votes from Sunday's contest, saying it was riddled with fraud. Lopez Obrador, who finished about 6.5 percentage points behind President-elect Enrique Pena Nieto of the Institutional Revolutionary Party (PRI), said the process had been corrupted by PRI vote buying and other abuses, and that his campaign would ask the Federal Electoral Institute (IFE) to recount the votes.
