Dear Ben,
Chavez being a Marxist was a funny one. After being president for ten years, and having all that oil cash, he gives a speech to the effect of ‘I assume Marxism, and also Christianity, Bolivarianism, Martianism, Sucrism and Mirandism.’ And then he admits that he never read The Capital. Reminds you of anything?
I do not know much about Maduro.
Castro was just as complicated as Lenin, and belongs in the same category. Was he a Marxist? The common debate on Castro is, conservative revolutionary or socialist nationalist.
