Overview
- INSA’s Sonntagsfrage puts the Union at 26% and the AfD at 25%, a narrow lead after several weeks when the AfD often polled ahead.
- The survey interviewed 1,202 respondents by phone and online from 25 to 29 August 2025.
- Party standings: SPD 15%, Greens 11%, Left 11%, BSW 4%, FDP 3%, Others 5%.
- Compared with February’s election, the Union sits about 2.5 points lower, while the AfD has gained just over four points.
- With roughly 12% polling below the 5% hurdle, a Bundestag majority could form with about 45% of votes, yet a CDU/CSU–SPD pairing would currently reach only 41%; separate polling shows 62% dissatisfied with the government and 57% with Chancellor Merz.
