Lula wins Brazil's presidential election, aided by a social media campaign

Brazilian President Luiz Inácio Lula da Silva won Brazil's presidential election on Sunday, securing another term leading South America's largest country.

An analysis by The New York Times says a large-scale social media campaign contributed to the victory. According to the newspaper, it convinced Brazilians to reject Lula's rival.
