Brazil prepares for close presidential vote

What happened

Brazil was due to vote on 4 October in a presidential first round dominated by President Luiz Inácio Lula da Silva and senator Flávio Bolsonaro. Both ended their campaigns with public events, and neither took part in a face-to-face debate. Polling pointed to a close contest and a likely runoff.

Questions

What could prevent a runoff?: A candidate would need enough backing on Sunday to win outright; otherwise, the two leading contenders proceed to a runoff.
Why did sovereignty feature in campaigning?: Lula made sovereignty central while warning about US interference; Bolsonaro framed his bid as the change Brazil needs.
How could Congress shape the result?: The president’s ability to govern will also depend on support from the centrist bloc, which seeks ministries and public resources.
Why are polls treated cautiously?: Survey leads differed across pollsters, and turnout concerns could affect a contest that news coverage described as closely fought.

Support and opposition

Who supports this, and why
