MEXICO CITY: Anti-establishment Leftist Andres Manuel Lopez Obrador swept to victory in Mexico´s presidential election Sunday, in a political sea change driven by voters´ anger over endemic corruption and brutal violence.According to exit polls, the sharp-tongued, silver-haired politician known as "AMLO" won by a large margin over his two main rivals, who both conceded defeat shortly after the polls closed -- laying to rest concerns that a deeply divided country could face prolonged uncertainty over the winner."I recognize his victory and express my congratulations, and I wish him the greatest of success, for the good of Mexico," said runner-up Ricardo Anaya, who ran for a coalition led by his conservative National Action Party (PAN).Jose Antonio Meade of the coalition led by the ruling Institutional Revolutionary Party (PRI) said the Leftist had "won the majority," adding: "I wish Andres Manuel the greatest of success."It is a major shift in Mexican politics: the PRI and PAN have governed for nearly a century, and Lopez Obrador will be the country´s first Leftist president in recent history.
