Actually, his ex-mistress just published a book about ol Hugo. After this mistress, he then went on to various other mistresses and, I believe, at least one wife. But he's like Castro: he believes it gives him more power if people know nothing about him. Castro, for example, had at least one child, a daughter who eventually wrote a book - about how her mother had been told never to breathe a word about the fact that Castro was her father, because Castro was supposedly "married to the revolution." I think Hugo is emulating his adored Castro in this too.
Very interesting. Looks like Chavez is also "married to the revolution".
