Polls opened early Sunday in Guatemala\'s runoff presidential election in an acrimonious atmosphere exacerbated by charges of vote buying. More than 7.3 million Guatemalans are eligible to take part in the polls pitting right-wing retired general Otto Perez Molina against businessman Manuel Baldizon. Ahead of the vote, Perez Molina said government officials were handing out vouchers for roofing and food supplies to the poor in exchange for their votes for businessman Manuel Baldizon. Perez Molina scored 55 percent, 10 points ahead of Baldizon, in polls leading up to the runoff to succeed President Alvaro Colom in Central America\'s most populous nation.
