Radar do Voto launches the Comparison Radar: up to 10 candidacies side by side, city by city, including the same candidate

Sep 24, 2026 · Radar do Voto Team

Put up to 10 candidacies side by side and see the vote of each in every municipality of the state: in percentage, in votes or against the candidate's own average. It works for president, governor, senator and deputy, from 1994 onward, and you can compare the same person in different elections. Free, on phones or computers. And, within a city, you can see down to the neighborhood and the school, from 2010 onward, in the elections for president.

The Comparison Radar by municipality: each column is a candidacy and each row, a municipality of the state, with the table sorted by the column of one of the candidates.

Update of October 5: Comparar is now called the Comparison Radar, and the 2026 election is already in it. See how it works now.

In which cities was one candidate stronger than the other? Where did someone grow from one election to the next? Answering that used to require opening result after result and building the table by hand. The Comparison Radar does it in seconds: you choose the state, add the candidacies and see the vote of all of them side by side, municipality by municipality.

Up to 10 candidacies fit at the same time, from any general election in that state, from 1994 onward: president (the presidential vote in the state), governor, senator, federal deputy and state deputy (district deputy, in the Federal District). Within the state, you can mix offices, years and rounds, and bring together the several candidacies of the same person to see how they evolved.

What is in the Comparison Radar

• By municipality: each column is a candidacy and each row, a municipality of the state. You choose how to read it: in % of valid votes, in votes or in vs. average. The % of valid votes is the candidate's share of the valid votes in each city, the best way to compare different offices. The vs. average shows how many points the candidate was above or below their own average in the state.
• Where each one was strongest: in the table by municipality, in % of valid votes, tap a column header and the table is sorted by that candidacy, from the city where it did best to the worst. In votes, the same order shows where it got the most votes.
• State totals: the vote of each candidacy added up in the state, in bars, to see the size of each at a glance. For president, it is their vote in that state.
• By neighborhood and by school: within a city, the vote of each candidacy in each neighborhood and, when you open the neighborhood, at each school (polling place). Here the mayor and city councillor of that city also come in, and the table shows the votes of each candidacy, with the neighborhoods in alphabetical order. This detail exists from 2010 onward: before that, the Superior Electoral Court (TSE) does not report the neighborhood of each polling place. It is free for president; for the other offices, including mayor and city councillor, the vote by neighborhood and school is paid.
• A person's track record: when you choose a name, that person's candidacies appear; with one tap on "Add all", the ones that work for the comparison come in at once (the candidacies for president, governor, senator and deputy in that state, from 1994 onward, up to the limit of 10), always in order of year, from left to right.
• Photo and ballot name: each column shows the photo (from 2010 onward), the ballot name and the year. When the full name differs from the ballot name, it appears on the candidacy label, above the table.
• Spreadsheet with the logo: download in Excel the comparison on the screen, ready for a news story, a class or a team meeting. The download is paid.

By neighborhood and by school, within a city: tap a neighborhood to open its schools (polling places). For president, it is free.

How to use it:

Select the state and type the candidate's name or ballot name. The search shows who ran in that state and also the presidential candidates, so you can see their vote there. Tap the person and then the candidacies you want to compare; repeat with the other names. To see by neighborhood and by school, go to "In a city", choose the city and add the candidacies on that page, which also accepts the mayor and city councillor of that city.

You can also get there from a candidate's profile on Radar do Voto: the Compare button opens the tool already in the state where the person ran, with their candidacies for president, governor, senator and deputy ready to add. For mayor and city councillor, use the "In a city" mode.

Examples to get started

• Compare the two candidates for governor who went to the runoff in your state, in % of valid votes, and sort the table by one and then by the other: the cities where each one was strongest appear.
• Put side by side the presidential candidate and the gubernatorial candidate of the same party, in % of valid votes, and see in which cities one was above the other.
• Add a deputy's candidacies and follow, in votes, municipality by municipality, how their vote changed from one election to the next.
• In your city, compare the 2022 presidential candidates in the first round and in the runoff, neighborhood by neighborhood and school by school. This breakdown is free.
• Within your city, put side by side, neighborhood by neighborhood and school by school, the votes of a city councillor and of a deputy. This breakdown is paid.

What it is for:

The Comparison Radar shows, quickly, where each candidate has strength and where they do not. It also shows how the votes of different names are distributed over the same territory and how someone's vote changed over the years. All with the TSE's numbers for each municipality, neighborhood and school.

Who it is for:

For voters who want to understand their own city and their own state. For journalists who need a ready-made table or want to dig deep. For teachers and researchers of electoral behavior. And for candidates, aides and teams who need to know where each name was strong and plan where to act.

Radar do Voto gathers and organizes public data from Brazil's Superior Electoral Court (TSE) and is not a primary source. In case of discrepancy, the TSE's data prevails.

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.
