Mexican President Vicente Fox transferred power to Felipe Calderon in a midnight ceremony today ahead of massive protests against Calderon’s inauguration. Opposition lawmakers are vowing to physically block Calderon from taking the constitutional oath before Congress. Supporters of presidential candidate Andres Manuel Lopez Obrador have accused Calderon of stealing July’s election. Lopez Obrador is planning to lead a major protest in Mexico City. Calderon’s inauguration comes as tensions remain high in the southern Mexican state of Oaxaca, where the federal police are attempting to crush a popular uprising.
