(Reuters) RIO DE JANEIRO — President Dilma Rousseff gained steam but remained locked in a dead heat for votes with challenger Aecio Neves ahead of Brazil’s Oct. 26 presidential runoff, an opinion poll showed on Monday.
Rousseff had 45.5 percent of voter support versus 44.5 percent for Neves, according to the survey by polling firm MDA, its first since the election’s first-round vote on Oct. 5. The difference between the two is statistically insignificant because it is within the poll’s margin of error.
Excluding undecided voters, spoiled and blank survey responses, Rousseff has 50.5 percent against 49.5 percent for Rousseff.
Recent surveys by the more closely watched Datafolha and the Ibope pollsters showed Neves slightly ahead of Rousseff, but within the surveys’ margin of error.
