A coup is possible but even within the Left many are upset with President Morales, the COB is creating its own party for workers, the road question, education policies and reform rather than revolution is another problem.
AS Ethan Earle has written in his recent article "Bolivia and the United States: A Relationship in Transition?" President Morales has started a rapprochement with the US starting this past November but as the US aid table to Bolivia shows below the (MAS) government of Morales has also received economic aid, besides the military aid and assistance during the falling out that started in 2009 but some programs recieved none and where others decreased and along with the resumption of limited military training that started recently in the US, all this is a cause for concern .
Also according to some news sources, Bolivia's government has deployed 2,300 troops onto the streets of its four largest cities (La Paz, El Alto, Cochabamba, and Santa Cruz) , following protests in El Alto over insecurity connected to the recent murder of two journalists.The soldiers began carrying out patrols with the police under the National Safety Plan and will last at least 3 months and along with the court of inquiry against the 17 main leaders of the last march."Indigenous Peoples Denounce Legal Persecution" http://upsidedownworld.org/main/bolivia-archives-31/3533-bolivia-tipnis-conflict-indigenous-peoples-denounce-legal-persecution we all should keep on eye on events happening in Bolivia.
And as of this weekend the COB trade union is still supporting the upcoming march and more will be known by the end of next week if not sooner
