Mexico's "Yo Soy 132" Youth Movement Erupted During 2012 Election

This Internet-driven movement didn't alter the outcome of Mexico's July 2012 presidential election -- since the candidate being "imposed" by the two major TV networks ended up winning.  But the student activists of Yo Soy 132 had impact; they set up an historic presidential debate that was carried online (the TV-promoted frontrunner, Enrique Pena Nieto, was the only candidate who didn't up).  It was this YouTube video that launched the movement, after a campus protest had embarrassed Pena Nieto.
