Brazil's right-wing presidential candidate Jair Bolsonaro appears ready to ride an anti-corruption wave into power. Bolsonaro came only four points short of winning the presidency outright on Oct. 7. He now faces leftist Workers' Party candidate Fernando Haddad, who received 29 percent of the first-round vote, in an Oct. 28 runoff. Polling shows Bolsonaro comfortably ahead . A scandal at Brazil's state oil company Petrobras in 2014 swept aside many potential candidates who otherwise would have posed a significant challenge to Bolsonaro, and his populist assurances to be tougher on corruption than his Workers' Party predecessors are resonating with voters, despite the relatively vague anti-corruption platform he has put forward. Whoever wins the election will enter office with a mandate to pursue stronger measures to investigate and penalize corruption. However, the next administration may find it difficult to match the pace of the indictments and prosecutions of the Petrobras investigation.
