Context: Brazil’s election entered the decisive round with close polls and extended voting due to logistical problems
Polls published a few days earlier placed Luiz Inácio Lula da Silva and Flávio Bolsonaro neck and neck or nearly so: a Datafolha survey gave both candidates 50%, while other research (Quaest) indicated a small difference, with Bolsonaro slightly ahead. In the first round, on October 4, Flávio Bolsonaro had secured an advantage in polls and provisional counts, and after 47% of the ballots had been partially counted, he was reported at approximately 50.20%, compared with 41.63% for Lula.
Meanwhile, Sunday’s election was marked by procedural adjustments: Flávio Bolsonaro later cited the extension of voting hours by two hours, a decision adopted following reports of transportation problems and heavy rains.
