Elections move the world.
Radar do Voto makes sure no chapter of that story is lost.
We keep political memory alive so you have what you need to make the best choice with your next vote.
Every election leaves a trail: who ran, for which party, how many votes they got, who won.
Even so, four years later almost no one can say who ran for mayor of their own city.
Radar do Voto keeps that memory and hands it back ready to read, on your computer or your phone, in seconds.
Some questions no one answers well
Who is this candidate? The name came up on the radio, on a campaign flyer, in the family group chat. Have they run before? For what office? How many votes did they get? Did they win?
How many votes does it take to elect a city councillor in my city? Or a deputy in my state? Anyone who has run for office has asked this. So has anyone who thought about running. And some people just wanted to understand why a relative with many votes was left out while someone with far fewer got in.
The answer clears up the most common confusion in Brazilian municipal and state politics. In 2024, in 4,718 of the 5,546 cities, someone who was not elected got more votes than the last person elected. The same happens in the states: in 2022 it happened in 26 of the 27 states for federal deputy, and in all 27 for state deputy. It is not a counting error: under Brazil's proportional system the seat belongs to the party before it belongs to the candidate. We show both side by side, city by city, state by state.
What is in Radar do Voto?
34 elections in one place. The make-up of the legislatures in each period. Votes for every candidate, every party, every city, every state, votes cast abroad and even states that no longer exist.
And what we are proudest of: the same person, recognized across a whole lifetime. Someone who ran in 1962 and again in 2024 (more than six decades on the ballot) appears on a single page, with everything in between. It is the difference between knowing the result of one election and knowing a political career. There are more than 2.3 million candidates, from 1933 to 2026.
Before Brasília, the Federal District was the city of Rio de Janeiro itself; when the capital moved in 1960, that city became the state of Guanabara, which elected a governor and is here under the name it had at the time. It was not the only unit to disappear from the map: Guaporé (today Rondônia) and Rio Branco (today Roraima) also appear, each under its name of the time. Anyone opening an election from 1962 needs to find the Brazil of that year, not today's. That is why, as you browse the site, you will find technical notes explaining the particulars of each period.
A passion for politics, transparency, education and memory
Politics is part of our lives, like it or not: we truly believe everyone needs to understand at least a little politics so we can build a better Brazil.
Transparency is our best guide: the easier it is to look up what already happened at the ballot box, the better each person decides their next vote. We bring together the electoral data as the TSE recorded it.
Education is our future: a history teacher, from primary school to university, can open the site to explain Brazil's different periods to a class, show the votes of historical figures, show the party make-up in a given period, and much more.
Memory is our foundation: anyone can now see how many votes they got in a race decades ago, or see the votes of a late father or grandfather, which party he belonged to and who his colleagues were in a given legislature at the time.
It is free, and it will stay free
Looking things up costs nothing, and it never will. No election, no candidate and no city is behind a paywall.
But to keep the site free we sell services and products to people who need more than a simple lookup. We would rather explain this than pretend it does not exist. A site about transparency that is not transparent about itself starts off on the wrong foot.
We ask just one thing: help us by sharing the site and, whenever you use it, mention the project and tag our Instagram: @radardovotobrasil.
