The double shooting comes months before Brazil’s presidential election in October. The violence is a sign of growing political polarization between the country’s two main parties. Former Brazilian President Luiz Inacio Lula da Silva is the PT’s candidate and currently leads Bolsonaro, who is running for re-election, in the polls. Bolsonaro has hinted that there is a possibility that he will not accept any electoral defeat. He has already cited unsubstantiated allegations of electoral fraud and issues with Brazil’s electronic voting system. After Saturday’s shooting, Bolsonaro said he refused “support from those who use violence against opponents,” in a statement on Twitter. With Post cables
