The Collapse of the Establishment: AfD Hits 40 Percent in Brandenburg as CDU Plummets

The political establishment in Germany’s eastern state capitals continues to face a stark reality as voter allegiance to traditional parties vanishes. The latest survey out of Brandenburg demonstrates far more than a routine fluctuation in public opinion; it exposes a profound shift where mainstream parties are effectively being reduced to political footnotes.

According to the fresh INSA opinion poll, conducted on behalf of the MAZ, MOZ, and Lausitzer Rundschau, the Alternative for Germany (AfD) has climbed to 40 percent of the vote. This represents a substantial surge of six percentage points compared to the previous survey taken on March 21. For the traditional governing parties, the numbers offer little comfort, but for the Christian Democratic Union (CDU), the result is nothing short of catastrophic.

The CDU witnessed its support disintegrate by five percentage points, dropping into single digits at a mere nine percent. The Social Democrats (SPD) did not escape the downward spiral either, forfeiting four points to land at 20 percent. With these figures, the AfD now commands twice the support of the ruling SPD in Brandenburg. Smaller players offer no alternative stability: Bündnis Sahra Wagenknecht (BSW) lost a point to settle at seven percent, tying with Alliance 90/The Greens, who gained two points to reach seven percent. Remaining political groups account for eight percent.

Brandenburg’s political reality is not an isolated case of voter discontent. The 40 percent threshold has increasingly become the baseline rather than an exception across the former eastern states. Recent polling places the AfD at 42 percent in Saxony, 43.8 percent in Saxony-Anhalt, and 40 percent in Thuringia. Even in Mecklenburg-Western Pomerania, where the September 20 election saw the party finish slightly under that milestone at 38.2 percent, the broader dynamic remains entirely consistent.

What these numbers reveal is a systemic failure of the conventional political class to retain its voters. When a once-dominant force like the CDU drops to nine percent, it suggests that standard political management is no longer convincing anyone. While 40 percent does not grant an absolute majority, it renders traditional coalition arithmetic increasingly absurd. The establishment now confronts a landscape where its moral authority and electoral viability have broken down in equal measure.
