Overview
- The Dec. 2–4 Datafolha survey interviewed 2,002 voters in 113 municipalities with a margin of error of plus or minus 2 points.
- An early‑September uptick stalled, leaving results statistically unchanged from September’s 33% positive and 38% negative readings.
- The new income tax exemption for earnings up to R$5,000 correlated with a four‑point approval increase among voters making two to five minimum wages, still within the subgroup’s margin of error.
- The snapshot lands as Jair Bolsonaro was jailed after his conviction became final and as Lula engaged a diplomatic thaw with Donald Trump that rolled back some U.S. tariffs on Brazilian products.
- Political headwinds include friction in the Senate over Jorge Messias’s STF nomination and public‑security tensions following a deadly Rio police operation.
