Dissidents and Politics in Cuba http://www.counterpunch.org/hernandez03302010.html

These opposition groups are not essentially different from the Cuban exiles in their methods and objectives. The most powerful anti-Castro organizations in Miami and New Jersey today no longer support war with bombs and armed groups. Dissidents and exiles do not agree on everything (for example, support for the embargo) but they share the same objective (to replace the system with a capitalist model), a common ideological denominator (anti-Castroism and anti-socialism) and the same allies (the United States, anti-communist governments and parties in Europe and other countries).

Their political nature is not captured with the adjective "mercenary," since it is likely that many, though they may receive money from the United States, have authentic ideological beliefs. Under the umbrella group Convergencia Democrática, a wide variety of interests, personalities and tendencies are associated; but their core tendency is toward the center-right. Although this partly explains their lack of acceptance in Cuban society, the main reason it is not a viable movement is that it lacks two essential political ingredients: leadership and legitimacy.
