The results of the Brazilian elections will reach the screens quickly, but between the last vote and the national percentage there is a sequence of operations. Understanding it will help to interpret the counting this Sunday, October 4, and to distinguish the result of a polling station from the balance of the entire country.
The first step occurs when voting ends in each section. The electronic ballot box calculates the registered votes and prints a document, the ballot box bulletin, which collects the local result. That record exists before its figures are incorporated into the national total.
What the ballot box bulletin contains
The document details the votes obtained by the candidates and other voting data. Five mandatory copies are printed, and one of them is placed on the door of the room used as a polling section.
Afterward, the stored data is sent to the Electoral Justice systems. As explained by the Superior Electoral Court (TSE), the ballot box is not connected to the internet or other data networks: the transmission of the result is carried out through a separate procedure.
Before incorporating the file into the count, the system checks its authenticity and integrity, including the digital signature that allows verifying its origin.
Why the first percentages may change
The national publication advances as the results from the sections are received and processed. Therefore, a candidate may rise or fall during the counting without the already registered votes having changed: the set of incorporated results changes.
A partial result also does not constitute a representative sample of the country by itself. To interpret it, one must observe how much has been counted and from which territories the data comes, in addition to the distance between the candidates. It is a caution in reading the recount, not a prediction about who will start ahead.
How to verify the official figures
The Results Portal and the TSE application allow consulting the totalization and accessing information by territory. They also show the number of processed sections and participation data.
The available documentation allows contrasting the bulletin of a section with the result incorporated into the system. The TSE also offers the Boletim na Mão tool to read the QR code of the printed document and consult its content.
What to do with the images of results that circulate beforehand
A photograph of a bulletin corresponds to a specific section. Although it is authentic, it does not allow proclaiming the national winner nor does it replace the aggregated count.
The official dissemination of the presidential result will begin at 17:00 Brasília time. This rule includes the votes received from abroad. Until then, and during the entire count, the origin, the time, and the territorial scope of each figure will be as important as the percentage shown.
