Radar do Voto goes live
Aug 11, 2026 · Radar do Voto Team
The main platform is free: search any candidacy and result, from 1933 to 2026, on phones or computers. Every Brazilian election, candidacy by candidacy and vote by vote, in one place.
We chose the 11th of August to begin. It was on this day, in 1827, that Emperor Pedro I created Brazil's first law schools: Largo de São Francisco, in São Paulo, and the one in Olinda, in Pernambuco. The country had just become independent and gained its first Constitution, and it needed to train people capable of thinking about and running the institutions that were being born.
From the benches of Largo de São Francisco came presidents, ministers, poets and jurists. More than a school, the place became the symbol of a simple and powerful idea: that citizenship is exercised with information in hand. Not by chance, August 11 is marked on the calendar as the day of students and lawyers.
It is in this spirit that Radar do Voto is born. Our starting point is the data from Brazil's Superior Electoral Court (TSE), from 1933 to 2026: every candidacy, every office, every result. What we do is turn this mountain of numbers, today locked in files that almost no one opens, into something anyone can read and navigate.
The main platform is free:
Searching any candidate, your city and any result, from 1933 to 2026, is open: without paying anything and without signing up. You see each person's entire track record at the polls (how many elections they ran in, for which offices, how many votes they got and where they were elected) and find out how many votes it takes to elect a city councillor, and why sometimes the candidate with the most votes is left out while another gets in through the party's remainder seats.
Explore the presidential map of the whole country, state by state and municipality by municipality, from 1945 to 2022: who won in each corner, the vote of Brazilians abroad and participation (turnout, abstention, blank and null votes). All colored on the map, all free.
For those who run campaigns, the open map:
There is also the Mapa do Voto, the dashboards for your state and your city. They take the data down to the neighborhood and the school: where each candidate was strong or weak, which are their strongholds, where the free vote to be won is and the scenario taking shape for 2026.
There are two levels. The Analysis, with the full history of the general elections from 1994 to 2022. And the Opportunity, focused on planning for 2026, which shows where the votes still up for grabs come from. It is the difference between deciding the campaign in the dark and deciding with the map open on the table. The map is free: compare candidates, see percentages, votes and where each one is strongest, city by city.
Our work is to make it within everyone's reach: a candidate, a journalist, a researcher or just a voter curious about their own city.

Radar do Voto is an initiative to make Brazilian politics more transparent and within everyone's reach: from elections to legislative amendments, we bring together in one place what was scattered and hard to find, so anyone can understand it and keep watch with information in hand. If you believe in this, help us go further: share it with friends, family and people who work in politics.
