Andres Manuel Lopez Obrador, presidential candidate for the Democratic Revolution Party (PRD), speaks during a news conference in Mexico City, Tuesday, July 3, 2012. With 99 percent of the vote tallied in the preliminary count, Lopez Obrador trails by just six percentage points behind the election's apparent victor, Enrique Pena Nieto of the Institutional Revolutionary Party, or PRI. The narrower-than-expected margin is fueling suspicion among Lopez Obrador's followers about the fairness of the vote. Lopez Obrador said he would not accept the preliminary election results reported by the Federal Elections Institute and would wait until Wednesday, when the official results are to be announced, before deciding what he will do.
