What happened, for context

Two polls released in mid-August 2026 show Brazilian President Lula leading Senator Flávio Bolsonaro (the eldest son of former President Jair Bolsonaro) in potential runoff scenarios ahead of Brazil's October presidential election, though the margin has narrowed since prior surveys.

Not yet confirmed against a primary source

  • Confirm the publication date of the CNT/MDA poll: en.mercopress.com states it was 'released on Tuesday' but does not specify which Tuesday. The article references a June comparison but provides no specific release date. This is needed to verify whether both polls were released in the same time window (mid-August 2026) or whether they are separated by weeks.
  • Confirm which Quaest poll the Reuters/Therint.in article refers to as 'August 5 Quaest poll': the body states 'An August 5 Quaest poll had Lula leading Bolsonaro by 44% to 39%' but then reports the current poll (August 10-13) at 43% to 40%. Verify this represents two distinct surveys rather than a transcription error.
  • Verify the sample frame for both polls: neither the CNT/MDA (en.mercopress.com) nor the Quaest (theprint.in) articles state whether respondents were registered voters, adults, or another population. This is standard polling metadata necessary for readers to evaluate the polls' applicability.
