Brazilians yesterday began casting ballots in their most divisive presidential election in years, with a far-right politician promising an iron-fisted crackdown on crime, Jair Bolsonaro, the firm favorite in the first round. If Bolsonaro gets more than 50 percent of the vote to lead the field of 13 candidates, he will win the presidency outright. Otherwise, a run-off will be held on October 28.
