Brazilians vote tomorrow in a presidential election that polls indicate is so unpredictable it could result in a first-round victory for incumbent Dilma Rousseff or a runoff between her and either of her two main challengers.
The incumbent is less than seven percentage points away from clinching a second term tomorrow, while Senator Aecio Neves gained ground, leaving him statistically tied with former Environment Minister Marina Silva in second place, according to an Oct. 3-4 Datafolha poll. Neves rose three percentage points since the the last Datafolha poll released Oct. 2, while Silva dropped two points, according to the poll, which has a margin of error of plus or minus two percentage points.
