Introduction to SiC Coverage

Brazilians vote on 4 October, with a runoff on 25 October if no candidate clears fifty percent. President Luiz Inácio Lula da Silva, eligible for a fourth term, was confirmed at the Workers' Party convention on 2 August with Geraldo Alckmin again as running mate. He faces Senator Flávio Bolsonaro, who received his imprisoned father's endorsement on 6 December 2025 and was confirmed as the Liberal Party's candidate. Registration closed on 15 August.The race is close and closing. Public security is both the terrain on which the challenger is strongest and the issue on which the incumbent is most exposed — and it is the only major question in the campaign on which a foreign government has intervened by way of a formal legal act.
