Brazil approaches the closing of the polls with two different questions: who will get the most votes and whether any of the candidates will gather enough to avoid a second round. At 21:00 in peninsular Spain, 16:00 in Brasília, voting continues. The dissemination of the presidential count is scheduled to start at 22:00, according to the calendar of the Superior Electoral Court.
When the results start to arrive, the first position will concentrate attention. But the margin between the candidates will also have a political reading. The 2022 elections left an eloquent precedent: Lula finished the first round with more than six million votes ahead of Jair Bolsonaro and won the second by just over two million.
Now he faces Flávio Bolsonaro. The change of candidate and context prevents mechanically transferring that result, although it allows recalling that a favorable first round does not resolve the Presidency.
From 6.18 million advantage to 2.14 million
In the first round of 2022, Lula received 57,259,504 votes, 48.43% of the valid ones. Jair Bolsonaro obtained 51,072,345, 43.20%. The difference was 6,187,159 votes and 5.23 percentage points. Neither reached the majority needed to win without a new vote.
In the second round, Lula rose to 60,345,999 votes and Bolsonaro reached 58,206,354. The final result was 50.90% against 49.10%: a distance of 2,139,645 ballots, equivalent to 1.80 points.
Both candidates gained support, but Bolsonaro grew more between the two dates. Lula's advantage was reduced by about four million votes.
What it means to finish first tonight
To win the Presidency in the first round, it is necessary to surpass half of the valid votes. Blank and null votes do not count in that calculation. If no one reaches that threshold, the top two will go to the second round on October 25.
In that scenario, finishing first would offer a favorable position for the next campaign, but no additional votes: the second round begins with a new vote.
The difference between the finalists will allow measuring the distance that the one who finishes second would have to recover. It will also matter how much support the eliminated candidacies have gathered, without assuming that their voters will automatically follow the recommendations of their leaders.
A provisional advantage is not a definitive result either
Before interpreting those margins, we will have to wait for the totalization to progress. The TSE will incorporate the data as it receives and processes the reports from the ballot boxes; the first figures do not equate to the result of the entire country.
The lesson from 2022 is not that the same evolution will repeat itself. It is that even a lead of millions of votes can narrow considerably between two rounds. Tonight Brazil will decide whether to elect a president or to open another three weeks of campaigning.
