Take some disparate facts, add some speculation, sprinkle in some ideology, then stir them together and serve up a tasty bowl of conspiracy theory. Eva Golinger, who is known for arguing at the far fringes of credulity, puts together a mashup of arguments to show why she thinks the U.S. government murdered Hugo Chávez by somehow giving him cancer.
I like this part in particular:
La naturaleza agresiva y desconocida de la enfermedad del Presidente Chávez, además de la inexistencia de una herencia de cáncer en su familia, apuntan claramente a la real posibilidad de que el líder de la Revolución Bolivariana haya sido asesinado.
The "unknown" part of the cancer, of course, is related to the fact that the Venezuelan government refused to tell anyone anything and lied constantly about the president's condition. The conspiracy, then, is internal. And aggressive? Every one of us knows someone who died tragically and quickly from cancer, even though just days before they were fit and healthy.
Go ahead and read the whole thing. At the very least, I believe she's managed to convince herself.
