# 2024 Curitiba mayoral election

The 2024 Curitiba mayoral election took place on 6 October 2024. Voters will elect a mayor, a vice mayor, and 38 councillors. The incumbent mayor, Rafael Greca (PSD) isn't eligible for a new term, since he was elected in 2016 and reelected in 2020.
If the most voted candidate on the first round doesn't achieve more than 50% of the votes, a second round will happen on 27 October 2024. The mayor's term will begin on 1 January 2025 and end on 31 December 2028.

## Context
### 2020 election

The last mayoral election in Curitiba, held in 2020, resulted in the victory of incumbent Rafael Greca, from the Democrats (DEM), in the first round. Greca obtained 499,821 votes or 59.74% of the valid votes. In the second place, the state deputy Goura Nataraj, from the Democratic Labor Party (PDT) only obtained 110,977 or around 13.26% of the valid votes and the other candidates did not reach double digits in vote percentages.
Greca's victory in the first round is linked to the enormous popularity he had and still has in the city. In December 2023, the mayor's management was approved by around 73% of Curitiba's inhabitants. As he is in his second consecutive term, Greca cannot run for re-election, due to limitations imposed by the Federal Constitution. There is speculation that the current Vice Mayor of Curitiba, Eduardo Pimentel, will be his successor.

### Electorate

In February 2024, Curitiba had around 1,419,395 people eligible to vote, an increase of 5% in the electorate compared to the last election and around 80% of the city's population eligible to vote (1,773,718), according to the 2022 Brazilian Demographic Census. The city is divided into ten electoral zones (1st, 2nd, 3rd, 4th, 145th, 174th, 175th, 176th, 177th and 178th). Voters have until 8 May 2024 to make their first copy of the electoral title or regularize it with the biometric registration.

### Declined to run

* Bruno Meirinho (PSOL) – Candidate for mayor of Curitiba in the 2008 elections and in the 2012 elections. Lawyer. The Socialism and Liberty Party, in a board meeting, decided on 13 April 2024 to officially support the potential candidacy of Andrea Caldas, thus removing the possibility of Meirinho becoming the party's nominee in the election.
* Deltan Dallagnol (NOVO) – Member of the Chamber of Deputies from Paraná (2023) and retired federal prosecutor. The former Lava Jato prosecutor announced the withdrawal of his potential candidacy on 3 May 2024. He states that he will dedicate himself to campaigns and the training of his own party's politicians throughout Brazil.
* Carol Dartora (PT) – Councillor of Curitiba (2021–2023) and member of the Chamber of Deputies from Paraná (2023–present).
* Zeca Dirceu (PT) – Mayor of Cruzeiro do Oeste (2005–2010), member of the Chamber of Deputies from Paraná (2011–present) and businessman.
* Felipe Mongruel (PT) – Lawyer.
* Paulo Martins (PL) – Member of the Chamber of Deputies from Paraná (2016; 2019–2023) and journalist. The Liberal Party nominated Martins as the running mate of Pimentel on 25 May 2024.
* Ricardo Arruda (PL) – Member of the Chamber of Deputies from Paraná (2013) and member of the Legislative Assembly of Paraná (2015–present).
* David Antunes (Cidadania) – Coordinator of Casa LGBT CWB and candidate for state deputy in the 2022 Paraná state elections.
* Goura Nataraj (PDT) – Councillor of Curitiba (2017–2019), member of the Legislative Assembly of Paraná (2019–present), candidate in the 2020 Curitiba mayoral election and philosopher.
* Beto Richa (PSDB) – Member of the Legislative Assembly of Paraná (1995–2001), Vice Mayor of Curitiba (2001–2005), Mayor of Curitiba (2005–2010), Governor of Paraná (2011–2018), member of the Chamber of Deputies from Paraná (2023–present) and engineer.
The Workers' Party, through its National Executive, formally announced its support for the potential candidacy of former mayor Luciano Ducci on 27 May 2024. Due to this decision, it is unlikely that any of the party's potential candidates would be able to launch a candidacy. However, these former candidates can still have an appeal to the Workers' Party National Directorate, which has already signaled that it intends to support other candidacies from other parties that are supporting the government in the National Congress, such as the Brazilian Socialist Party (PSB) itself. Dartora and Mongruel decided to not appeal the decision of the National Executive, putting an end once and for all to the aspirations of having their own mayoral candidacies. Only Dirceu decided to appeal to the National Directorate. The appeal does not yet have a date to be analyzed. Along with the Workers' Party itself, the other parties that belong to the Brazil of Hope alliance, such as the Communist Party of Brazil (PCdoB) and the Green Party (PV), will also support Ducci's candidacy. Goura Nataraj was confirmed as Luciano Ducci's running mate on 24 July 2024, after his name was approved by the National Executive of the Democratic Labour Party.
David Antunes withdrew his candidacy for mayor on 25 July 2024 in order to build a strong ticket, with strong candidates for the Municipal Chamber of Curitiba in the October elections. At the same meeting, the party declared its support for Eduardo Pimentel's candidacy. On 5 August 2024, Beto Richa withdrew his candidacy. The reasons that led him to make this decision were: a lack of party political broadcast time to present his proposals and a disagreement between some groups of Cidadania with a possible support for his candidacy. Cidadania is a party that has a national alliance (Always Forward – PSDB/Cidadania) with the Brazilian Social Democracy Party. Richa defends the neutrality of his party in the election.
* Lawyer Bruno Meirinho (PSOL) from Curitiba
* Federal Deputy Deltan Dallagnol (NOVO) from Pato Branco
* Federal Deputy Carol Dartora (PT) from Curitiba
* Federal Deputy Zeca Dirceu (PT) from Umuarama
* State Deputy Ricardo Arruda (PL) from São Paulo
* Coordinator of Casa LGBT CWB David Antunes (Cidadania) from Piraquara
* Federal Deputy Beto Richa (PSDB) from Londrina

### Candidacy under legal review

On 26 January 2024, the Brazilian Woman's Party (PMB) announced the journalist Cristina Graeml as a potential mayoral candidate for the Curitiba City Hall. She left Gazeta do Povo, where she worked as a columnist from January 2020 to April 2024, to run for the position. However, there was uncertainty regarding the party convention that would officially confirm her candidacy in August due to a legal dispute involving the National President of PMB, Suêd Haidar, and the local party executives in Paraná. On 3 August, Haidar decided to dissolve the local PMB executives and removed Geonísio Marinho from his position as the municipal president of PMB Curitiba to prevent the convention that would officially confirm Graeml’s candidacy. Despite this, the convention was confirmed by the state president of the PMB Paraná Executive Committee, Fabiano dos Santos, and took place as scheduled on the evening of 5 August. Cristina Graeml’s candidacy was officially confirmed, and the slate of candidates for the Municipal Chamber of Curitiba by the PMB was also formalized at the same event.
The legal dispute is ongoing, and on the last day of the convention, the local executives of PMB in Paraná and Curitiba filed a writ of mandamus with the Regional Electoral Court of Paraná (TRE-PR) to contest the legal effects of the National Executive’s intervention. On 7 August 2024, the electoral judge Cláudia Cristina Cristofani ruled that the state electoral court did not have jurisdiction over the case. She argued that, since it involved a decision by the National Executive of the Brazilian Woman's Party, the Superior Electoral Court (TSE) was the appropriate body to decide the matter and determine the status of Cristina Graeml’s candidacy. The case has not yet been scheduled for a hearing by the Superior Electoral Court.

## Debates

Below is a list of the mayoral debates scheduled or held for the 2024 election (times in UTC−03:00).
Due to the crisis that unfolded within the Brazilian Woman's Party (PMB) following the dissolution of the local executives by the National Directorate and the suspension of Cristina Graeml's candidacy, she was not invited to the first Band debate. The conglomerate announced the decision of not inviting Graeml to the debate on the evening of 8 August. She criticized Band Paraná for considering the decision to 'uninvite' her from the debate as undemocratic, especially after she had arrived at the broadcaster at the scheduled time and was forced to return home, stated that she had prepared for the debate and, while the event was being broadcast on television, she hosted a live stream on social media to answer the questions directed at the other candidates.

## Opinion polls
### Polling aggregator

The CNN Index, developed by CNN Brazil and Ipespe Analítica, does not present sampling numbers or specific collection periods because it does not conduct its own polls. Instead, it aggregates and adjusts data from various polls conducted by different institutes, using statistical techniques and machine learning. The index provides an overview of voting intentions in 100 cities, including capitals, and is constantly updated based on the latest available data. Additionally, the CNN Index typically highlights only the top five candidates, potentially leaving out other relevant candidates.
