Mexico: the Drug War and Sunday's Presidential Election

Mexico is in the throes of a war against drug cartels that's killed more than 50,000 people. Four days before Sunday's presidential election in Mexico, the return of the Institutional Revolutionary Party (PRI) is widely predicted. That's the party that governed for 71 years until it was rejected 12 years ago. What's happened to the promises of real democracy and the end of corruption? With 43 percent of the voting population under 30, will a growing youth movement that began on college campuses and that's spreading on social media make a difference?
