Both extremes of the Cuban political spectrum and the filling between both sides use marches and demonstrations to make a point. The pseudo-revolution in Cuba and the exile traditionalists enjoy a good parade more than reaching the goals they pretend to impulse with them. The triumph Communists get out of these mass demonstrations and the failure their opponents get out of them lie precisely here.
Communists control the mass media in Cuba.
Any mass demonstration by the masses and for the masses immediately connect both ends successfully. Their masses see their mass demonstrations in their state-controlled mass media. It cannot work in Miami where the control of the second leg of the process does not exist. Out of Miami and in Spanish, such demonstrations are ignored elsewhere. In fact, the more demonstrations exiles produce, the more ignored they are taken seriously by the international media.
