Rousseff regains edge in Brazil presidential race as Silva slips
BRASILIA (Reuters) - President Dilma Rousseff has regained a slight edge in Brazil's presidential race after weeks of aggressive campaigning against environmentalist Marina Silva, who is losing some voter support in the campaign's homestretch, polls showed on Tuesday.
Rousseff and Silva are tied at 41 percent in a likely second-round runoff that is expected to decide the election, according to a survey by the Ibope polling firm.
Another survey by MDA showed Rousseff would get 42 percent of the votes against 41 percent for Silva if the runoff were held today, a one point advantage that amounts to a statistical tie as it is within the poll's margin of error.
Silva, who would be Brazil's first black president, was leading polls on the runoff before the Rousseff campaign unleashed a wave of negative campaign ads questioning Silva's ability to lead Latin America's largest economy.
