Almost half of Brazilian voters disapprove of President Luiz Inácio Lula da Silva's government, according to a nationwide Quaest survey released on Monday.
The poll found that 49 percent of respondents disapprove of the federal administration, while 46 percent approve of its performance. Another 5 percent of those surveyed said they did not know or did not answer.
The results show a slight narrowing of the gap compared with the previous Quaest survey, in which 50 percent of respondents disapproved of the government and 44 percent approved. In that earlier poll, 6 percent did not know or gave no response.
Public evaluation of the federal administration
The survey also examined how voters evaluate Lula's day-to-day management in the presidency. A negative perception was reported by 41 percent of respondents, while 34 percent evaluated his administration positively.
A further 23 percent of voters classified the government as regular, viewing it as neither distinctly good nor bad. The share of respondents who did not know or did not provide an answer stood at 2 percent.
Those numbers reflect minimal movement from the prior round of research. In that earlier poll, negative ratings stood at 42 percent and positive reviews reached 33 percent, while 23 percent considered the administration regular and 2 percent were undecided.
Lula, who co-founded the left-wing Workers' Party, known in Brazil as the Partido dos Trabalhadores or PT, returned to power for a third non-consecutive term following his earlier presidencies between 2003 and 2010. Governed from the Palácio do Planalto in the federal capital of Brasília, the administration has faced close legislative scrutiny and deep political polarisation throughout the country.
Survey methodology and electoral court filing
The Quaest survey interviewed 2,004 people between September 24 and September 27. The study carries a margin of error of two percentage points, plus or minus, with a 95 percent statistical confidence level.
The research was commissioned by Brazilian media organisation Grupo Globo, the country's largest communications company. In accordance with Brazilian regulations, the poll was officially registered with the Tribunal Superior Eleitoral, Brazil's Superior Electoral Court, under tracking number BR-06520/2026.
Under national electoral laws, public opinion polls conducted ahead of elections must be registered with the Superior Electoral Court to ensure statistical transparency, disclosing methodology, sample distribution, and commercial sponsorship. Polling institutes and political parties will track these approval indicators over the coming weeks as government leaders and opposition figures assess voter support across Brazil.
