People watch the results on television during the vote count in the southern zone of Rio de Janeiro, Brazil, on October 25, 2026, during the presidential runoff election. Brazilians head to the polls for a runoff between President Luiz Inacio Lula da Silva and right-wing senator Flavio Bolsonaro that will determine whether Brazil remains one of the few leftist nations in the region or joins a regional swing to the right championed by US President Donald Trump, a Bolsonaro ally.
