Brazil's leftist president, Dilma Rousseff, narrowly won re-election Sunday after convincing voters that her party's strong record of reducing poverty over the last 12 years was more important than a recent economic slump.

After one of the closest, most divisive campaigns in Brazil in decades, Rousseff won 51.6 percent of votes in a runoff against centrist opposition leader Aecio Neves, who won 48.4 percent with more than 99 percent of the votes tallied.

At a hotel in Brasilia where Rousseff was due to speak, party supporters waved red flags and jumped up and down, screaming in celebration.
