Brazil poised to elect a new president
Brazil holds major elections Sunday and voters are set to elect a new president. Far-right candidate, Jair Bolsonaro, is considered a front-runner. He was recently stabbed at a campaign rally but has since recovered. Fernando Haddad, another leading contender, is known as a stand-in for Brazil's former president, Luiz Inácio Lula da Silva, who's now serving a 12-year jail sentence for corruption. CBSN contributor and Signal newsletter writer for GZero Media, Willis Sparks, explains why this election is worth watching.
