Brazil's leftist Workers Party candidate, Fernando Haddad, would defeat far-right candidate Jair Bolsonaro in an expected runoff vote in next month's election, a Datafolha poll showed on Friday. In a simulated runoff vote, the poll found Haddad would get 45 percent voter support, beating Bolsonaro with 39 percent. A second-round is required if no candidate wins a majority in the Oct. 7 first ballot, which is expected to happen.
