Macky Sall won the Senegalese presidential elections over the weekend.  He defeated Abdoulaye Wade, whose attempt to run for an illegal third-term sparked violence and protest throughout the country. Many feared he would refuse to step down from power, but he conceded after his defeat Sunday night. Columbia University professor Souleymane Bachir Diagne tells Worldview how this will impact the country. Also, Central American migrants who traverse Mexico without a visa face the risk of being raped, kidnapped, disappeared or killed. Worldview talks with Father Alejandro Solalinde and Cristian Pineda Flores, two Mexicans who advocate for migrants rights in Mexico. Salvadoran filmmaker Marcela Zamora Chamorro also discusses her award-winning documentary about the abuse and humiliation endured by migrant women who travel through Mexico.
