In the 2012 election, 850,777 people were eligible to vote in Goiânia,[2] which corresponded to 64.5% of the city's population, according to estimates from the Brazilian Institute of Geography and Statistics (Instituto Brasileiro de Geografia e Estatística – IBGE).

[6] Without the card, a regular Brazilian is unable to get a passport, to retire from the Social Security, to enroll in public schools or universities, to obtain a loan from state-run banks or to become a civil servant.

[2] On 6 October 2008, then mayor and former governor Iris Rezende, of the Brazilian Democratic Movement Party (Partido do Movimento Democrático Brasileiro – PMDB) was re-elected with 74% of the valid votes.

[9] Shortly before the definition of candidates for mayor, on 29 February 2012, criminal offender Carlinhos Cachoeira, which profited between 1 and 3 million reais (around 0.5 to 1.5 million dollars) per month[10] through the illegal jogo do bicho was arrested in Goiânia as a result of the Monte Carlo Operation, led by the Federal Police (Polícia Federal – PF).

[15] Two weeks prior to the Monte Carlo Operation, Torres announced that he would not run in order not to undermine the opposition to Dilma Rousseff's administration in the Congress.

[17] Another pre-candidate harmed by his relationship with Cachoeira was alderman Elias Vaz, from the far-left Socialism and Liberty Party (Partido Socialismo e Liberdade – PSOL), which had between 14% and 18% of the voting intention.

The offender paid the expenses of Marconi Perillo's gubernatorial campaign and bought a house that belonged to the latter (the same place where he was arrested by the PF), arranging for the purchase money to be delivered at the Emerald Palace (Palácio das Esmeraldas), seat of the state government.

[11] Federal deputy, Jovair Arantes, of the Brazilian Labour Party (Partido Trabalhista Brasileiro – PTB), which was cited by members of Cachoeira's group in wiretaps,[11] was chosen as the candidate of the Marconists and had the highest rejection rate throughout the campaign.

[29] Nevertheless, Garcia and Rezende filed a collective lawsuit against Alego; they claimed that it does not compete to the Assembly the investigation of contracts which are not funded by the state of Goiás.

[30] A week after the election, judge Luis Eduardo de Souza granted an injunction overturning Alego's intention of disclosing the personal data of both Garcia and Rezende.
