Brazil's President Dilma Rousseff has trimmed some of her losses in presidential voting intentions resulting from her country's social turmoil but would be forced into a runoff, a poll released Sunday showed.
Rousseff, who lost 21 percentage points in late June after the nationwide street protests over living standards and corruption, is now credited with 35 percent, up five points, for next year's poll, a Datafolha nationwide poll said.
Marina Silva, an environment icon and former senator who is trying to form a new party, is second with 26 percent, up three points from late June, ahead of Senator Aecio Neves, of the opposition Brazilian Social Democratic Party, or PSDB.
In a runoff, Rousseff would edge Silva by 46 percent to 41 percent and would win more than 50 percent against all other opposition candidates.
The poll, conducted between Tuesday and Thursday, was published by the daily Folha de Sao Paulo.
It found that if Rousseff's predecessor and mentor Luiz Inacio Lula da Silva were to run for the ruling Workers Party, he would win in the first round, ahead of Marina Silva.
Silva, who served as environment minister for five years from 2003 in Lula's government, is the only candidate who has been on an ascending curve in the presidential polls, even during the June protests.
The Datafolha poll surveyed 2,615 people and has a margin of error of two percentage points.
Another Datafolha survey published Saturday confirmed Rousseff's recovery.
It put the approval rating of her government at 36 percent now, up from 30 percent in late June when it dropped 35 percentage points in the wake of the massive street demonstrations.
Datafolha attributed the change to Brazilians' greater optimism about the country's economic performance, notably in the areas of inflation, purchasing power and unemployment.
