Today, Brazilians will choose between Bolsonaro's son and Lula.

On October 25, Brazilian citizens will vote in the presidential runoff between incumbent leftist Luiz Inácio Lula da Silva and right-wing candidate Flávio Bolsonaro. Bolsonaro, who received the most votes in the first round, has the support of Donald Trump. Historically, no candidate has overcome a deficit in the second round after trailing in the first. Bolsonaro's campaign focuses on tough measures against organized crime and promises tax cuts. Lula's Workers' Party frames the election as a struggle for democracy, accusing Bolsonaro of being a U.S. candidate and a threat to democratic institutions. Bolsonaro argues for cooperation with the U.S. to combat powerful gangs in Brazil, while Lula faces corruption allegations.
