Brazil runoff polls released October 19 show Flávio Bolsonaro’s lead over Luiz Inácio Lula da Silva narrowing before the October 25 vote, Reuters reports. Nexus has them at 46.5% and 45.9%; AtlasIntel reports 49.8% and 47.6%. Both gaps are smaller than in the respective earlier surveys. The victory confetti can remain in its original packaging.
Nexus interviewed 2,002 people October 16–18, with a two-point margin of error. AtlasIntel surveyed 4,998 October 13–18, with a one-point margin. These are measurements of reported voting intention, not votes counted or a forecast guaranteeing a winner.
The useful reading is narrower than either campaign’s preferred reaction. A tightening survey can be politically significant without proving that momentum will continue on a straight line. Voters do not move through the final week like a progress bar downloading an election result. There can be movement, noise, late decisions and differences between the people answering a poll and the people who ultimately cast ballots.
It also helps to resist building an imaginary super-poll out of incompatible pieces. Do not take one firm’s number for one candidate and another firm’s number for the opponent, then announce a dramatic new gap. Compare like with like, keep the fieldwork dates attached, and remember that a headline is not a replacement for the survey’s actual scope. Electoral arithmetic already has enough volunteer magicians.
Our take: the news is that the race looks more competitive in these fresh measurements, not that the election has secretly happened. A lead is a lead in a particular survey. It is not a government, a mandate or permission to skip the remaining campaign. The distinction becomes especially useful when both sides discover that the same data can be sold as either inevitable triumph or an inspiring comeback montage.
DJF’s earlier Brazil coverage concerned the election and fiscal pledges. This update concerns the new October 19 polling, with the runoff still ahead. We will leave the declarations of destiny to campaign headquarters. For everyone else, the sensible thing to keep on the refrigerator is the actual voting date, not a screenshot that has been promoted into a prophecy.
