Among Venezuelans taking to the streets are student protesters who, in the past, have proven to be a powerful political force. Using Twitter as well as street demonstrations, the students offer a boost to a weak and disjointed opposition. Tens of thousands of Venezuelans took to the streets of Caracas and other cities Wednesday in the biggest antigovernment protests yet during the 10-month term of President Nicolas Maduro. Pro-government demonstrators also turned out, sparking confrontations that reportedly left three people dead.
