Opposition wins in presidential elections in Mexico

Mexico's old rulers claimed victory in a presidential election on Sunday, ending 12 years in opposition after a campaign dominated by a sputtering economy and rampant drug violence, the Reuters reports.

After pledging to restore order and ramp up economic growth, Enrique Pena Nieto of the Institutional Revolutionary Party (PRI) had a clear lead over his rivals in exit polls and a "quick count" conducted by electoral authorities.

The second place candidate, leftist Andres Manuel Lopez Obrador, refused to concede, saying he would wait for a full count, the CBS reports.
