巴西总统罗塞芙承诺承诺政治改革

Brazil's left-leaning President Dilma Rousseff will have a second term in office after winning re-election on Sunday. In a narrow margin victory, Rousseff had 51.6 percent of the votes in a run-off against her centrist rival Aecio Neves. There were scenes of jubilation on the streets across Brazil to celebrate her re-election.

Exuberant scene at Brasilia this night.

Red flags were waved, and people jumped up and down, screaming in celebration when it was clear their leader was re-elected.

"Dilma represents me. A vote for Dilma is a vote for the people."

Rousseff addressed the crowd soon after her winning, acclaiming her victory.

"Today, I am a lot stronger, more serene and more mature for the work that you have delegated to me. Brazil, once again, this daughter of yours won’t walk away from the fight," Rousseff said.

In her speech, Rousseff said her first priority in a second term would be political reform, promising to work with Congress on changes that the country demands.

She also said her re-election represented the country’s hope and recognized the country’s desire that she work harder to be a "better president."

"A re-election vote is a vote of hope, especially for improving the actions of those who have been governing. I know that is what the people say when they re-elect a leader. That is what I’ve heard from the voting booths. That is why I want to be a much better president than I have been up until now." Rousseff said.

However, what behind the festive atmosphere, is one of the closest, most divisive campaigns in Brazil in decades.

Rousseff won only 51.6 percent of votes against his rival Aecio Neves, who won 48.4 percent. That means she won by only 2.7 million votes.

It’s clear that Brazilians were not sold on her policies, which she pledged to save Brazil from economic slump. And it is also clear that it will take her for a while to reunite the other half of the country who opposed her.
