Brazilians go to the polls this weekend, to elect a new president, replacing the charismatic Lula da Silva. And, with Dilma Rousseff far ahead in the polls, it looks like the country could get its first female leader. It's been an amazing journey for Rousseff, the daughter of a Bulgarian immigrant. In the 1960's, she joined a revolutionary urban guerrilla group after the military coup, and was imprisoned and tortured.
She is now seen as Lula's successor, nicknamed 'The Iron Lady', though there are questions about her own public charisma and in which direction she will take this booming country of 200 million people. If she wins, she could become one of the world's most powerful leaders.
