Brazilians voting in nail-biter election for president

Rio De Janeiro, Brazil: Brazilians were voting on Sunday in the most unpredictable presidential election in decades and the first since the end of an economic boom underpinning the leftist Workers' Party's 12-year rule.

As President Dilma Rousseff seeks a second term, voters are weighing whether the socioeconomic gains of the last decade are enough to reject the candidacies of a popular environmentalist and a pro-business social democrat, who both promise to jump-start the economy after four years of lackluster growth.
