Will students help Manuel López Obrador win?

Democracy Now!:

As the drug war rages in Mexico, voters will head to the polls on Sunday to choose a new president. Will the PRI come back to power, or could the Occupy-inspired Yo Soy 132 movement help Andrés Manuel López Obrador, a former Mexico City mayor who narrowly lost the 2006 election, pull off an upset? We go to Mexico City to speak with Tania Molina, a journalist at La Jornada, the main progressive national newspaper in Mexico; and John Ackerman, editor of the Mexican Law Review and a professor at the National Autonomous University of Mexico (UNAM).
