What looked like a cakewalk for incumbent Dilma Rousseff has turned into a tight race with old rival and ulra-green challenger Marina Silva. The only certainty is that Brazil will have another woman president, probably in a run-off following Sunday's vote.

Since 2000, the U.S. has deported more than 150,000 immigrants with criminal records to Central America, mostly in the last few years. Should we be surprised then at the surge in violence in the region, and the mass exodus of adolescents trying to reach America's borders.

Often touted as one of the most powerful women in the world, Brazil's President Dilma Rousseff suddenly finds herself atop a souring economy and electorate with elections only months away. The dramatic way Brazil crashed out of the World Cup hasn't helped, Robert Muggah writes from Rio.
