The September 6, 2026, Landtag election delivered a decisive outcome for the CDU vote share market, with preliminary official results placing the party at 17.2 percent—well below the 20 percent threshold and roughly halving its 37.1 percent share from 2021. This reflected a broad shift toward the AfD, which reached 43.8 percent amid record turnout of 77.8 percent, alongside weaker showings by the outgoing CDU-SPD-FDP coalition partners and the FDP’s failure to clear the five-percent hurdle. National factors, including economic conditions under Chancellor Friedrich Merz’s federal government, contributed to the CDU’s state-level decline. The certified final result scheduled for September 22 could produce minor adjustments from recounts, though any movement sufficient to exceed 20 percent remains improbable given the scale of the preliminary margin.
