Mexicans went to the polls on Sunday to choose a new president. The official preliminary vote count handed a victory to Enrique Pena Nieto. A win for the former governor of the state of Mexico marks a return to power for the Institutional Revolutionary Party (PRI). PRI controlled Mexico's presidency for more than 70 years until the election of Vicente Fox in 2000. Some fear the PRI’s re-emergence will bring a return of corruption and patronage to national politics. Issues facing the new president include a continuing drug war and sputtering economy. The Wilson Center's Eric Olson discusses the outcome of the Mexico presidential election on NPR's Diane Rehm Show.
