Traffic police stand underneath a sign reading "Today we, the youth, say no to fraud" while guarding the entrance to Mexico's Federal Electoral Institute (IFE) in Mexico City July 4, 2012. Mexico's election officials on Wednesday recounted votes from more than half the polling places from Sunday's presidential election after the leftist runner-up alleged fraud and asked for a recount. Andres Manuel Lopez Obrador, who finished about 6.5 percentage points behind the declared winner, Enrique Pena Nieto of the Institutional Revolutionary Party (PRI), said on Tuesday the election had been corrupted by PRI vote-buying and other abuses.
