The autumn 2026 state elections in Saxony-Anhalt, Berlin and Mecklenburg-Vorpommern signal more than a mid-term rebuke: They mark a structural crisis of the Merz chancellorship and raise fundamental questions about the Christian Democratic Union (CDU)'s viability as a governing force. This analysis examines the electoral, demoscopic and intraparty evidence, situates it within the structural conditions of German coalition politics, and considers the scenarios now defining the government's horizon.

The German political lexicon has a precise term for it: "Kanzlerdämmerung” – Chancellor’s twilight. It describes the gradual dissolution of executive authority through accumulating electoral defeats, falling approval ratings, and the withdrawal of intraparty support. As of late September 2026, that process has overtaken Friedrich Merz with a speed few observers anticipated when he took office in May 2025. The results expose not only the failure of his electoral strategy, but a deeper rift between the CDU's federal leadership and its regional base – one whose consequences extend well beyond any single chancellorship.

Electoral evidence

The Sept. 6, 2026 election in Saxony-Anhalt delivered what Merz himself called "the worst election defeat the CDU has suffered in years – or even decades.” The Alternative for Germany (AfD) recorded 43.8% of the party-list vote – the strongest result for any single party in the state since reunification – while the CDU fell to 17.2%, its worst result since 1990, losing all forty constituency seats it had previously held. An exit poll indicated that only 9% of Saxony-Anhalt voters approved of Merz’s performance as chancellor. The incumbent state's minister-president, Sven Schulze (CDU), publicly conceded that his party had lost its mandate to govern – a rare acknowledgment from a regional leader within the chancellor’s own party.

Two weeks later, the elections of Sept. 20 deepened the crisis. In Mecklenburg-Vorpommern, the CDU fell from 13% in 2021 to approximately 4.9% – below the 5% threshold for parliamentary representation, leaving it without Landtag seats for the first time since reunification. The AfD won 38.2%, claiming the state outright and more than doubling its previous result. In Berlin, the CDU finished second with around 20%, trailing the Left Party – reflecting an equivalent erosion in the party’s urban base. The cumulative verdict is clear: The CDU has ceased to function as a competitive governing force across large parts of eastern Germany.

Collapse in public approval

The electoral results did not emerge in a political vacuum. By mid-September 2026, German institute INSA's survey found that only 14% of Germans regarded Merz as the right chancellor, while 78% did not – including a majority of Union voters. The ARD DeutschlandTrend had recorded, in May 2026, only 16% satisfaction with his work, the lowest figure measured for any sitting German chancellor. In national polls, the AfD moved ahead of the CDU/CSU for the first time, registering around 28 to 29% against the CDU/CSU’s near-20% – an inversion that, if sustained, would represent a fundamental realignment of the German center-right.

The underlying problem is substantive. Political scientist Marc Debus has attributed the approval decline in part to voter disappointment with the pace of promised reforms. Economists Achim Truger and Tom Krebs have argued that Merz’s austerity-focused budget approach risks dampening demand at precisely the moment the German economy requires investment. Whatever the correct diagnosis, the political outcome is the same: The flagship Wirtschaftswende has not materialized in voters’ daily experience, while a package of structural reforms – pension age increases, healthcare restructuring, income tax changes – has generated broad public opposition.

Intraparty fracture

What renders Merz’s position particularly precarious is the erosion of intraparty solidarity. On Sept. 16, 2026, the eight CDU minister-presidents issued a collective statement arguing that restoring voter trust required "listening and taking political action, not debates over personnel.” Signatories included Kai Wegner, Boris Rhein, Hendrik Wüst, Michael Kretschmer, Sven Schulze, and Daniel Günther. The statement pledged to work "together with the chancellor,” but did not mention Merz by name. The omission was deliberate: Formally loyal in tone, the declaration functioned as an act of collective distancing that preserved each signatory’s room to maneuver.

Hendrik Wüst, minister-president of North Rhine-Westphalia and head of the CDU’s largest state organization, has been the most prominent figure in this dynamic. While formally endorsing Merz, he called on the chancellor to "solve issues and problems that people are dealing with in their daily lives” – criticism framed in the language of institutional encouragement.

Since May 2026, Wüst has emerged as the most frequently discussed alternative chancellor. His strong electoral record in the west gives him a credibility that Merz has visibly lost. Christian Social Union (CSU) leader and minister-president of Bavaria Markus Söder has adopted an equally conditional posture, his public warnings about coalition collapse widely read as contingent support rather than principled loyalty. Open dissent has emerged further down the party: A CDU deputy in Saxony-Anhalt described Merz as "unsuitable” for office, and a Junge Union official stated publicly that "with this chancellor, elections can no longer be won” – a departure from the customary discipline of German conservative politics.

Structural conditions of crisis

The Merz crisis cannot be reduced to personal failings alone. Three structural factors compound his difficulties.

First, the "grand coalition” formed in May 2025 was weak from the outset. The CDU/CSU and Social Democrats (SPD) together held 328 seats, giving them a majority of only twelve seats in the 630-seat Bundestag, leaving virtually no room for dissent. The "Brandmauer” (firewall) against any cooperation with the AfD, maintained by all mainstream parties, further constrains the government’s options, forcing the CDU into a partnership whose electoral base holds fundamentally different priorities on social spending, labor law, and fiscal policy. The July 2026 reform package illustrated this tension: already unpopular, it faced SPD demands for renegotiation that threatened to stall the government’s entire legislative program.

Second, the AfD's dominance in eastern Germany reflects forces that predate and exceed the present government. The party’s 43.8% in Saxony-Anhalt is the product of a decade-long realignment driven by structural economic disadvantage, demographic decline, and deepening estrangement from mainstream politics. A particularly acute grievance is the federal government’s financing of both the war effort in Ukraine and the reception of Ukrainian refugees – a combination that eastern German voters, who already perceive themselves as net contributors receiving inadequate return from the state, regard as a fundamental misalignment of priorities.

Survey data consistently show that skepticism toward arms deliveries and refugee costs is significantly more pronounced in the east than in western Germany, cutting across party lines and reinforcing the AfD’s narrative that the political establishment places distant commitments above citizens’ daily concerns.

What the 2026 results confirm is that this realignment has reached a qualitatively new stage: The CDU's displacement from its traditional role as the east’s dominant center-right party is no longer a cyclical setback but a durable structural shift. Merz's response, with harder rhetoric on migration, fiscal conservatism, and deregulation, was designed to contest the AfD on its own ground. Instead, it appears to have blurred the line between the mainstream and the radical right without recovering a single AfD voter.

Third, a series of internal controversies from July 2026 onward – the Jens Spahn surrogacy affair, a poorly handled cabinet reshuffle, a protracted dispute over a senior CDU official’s departure – independently damaged Merz’s image as a competent institutional manager. Political scientist Thomas Biebricher has identified the core failure: Merz never made a convincing case that short-term sacrifices would yield long-term improvement. The reshuffle’s handling, ministers learning of their dismissal through the press, reinforced the portrait of a chancellor assertive in posture but inconsistent in practice.

Three scenarios

Three possible outcomes have emerged from internal CDU deliberations. The first is a voluntary "Kanzlertausch”: Merz steps aside, and the Union designates a successor, who will most likely be Wüst, to lead the existing or a renegotiated coalition. The second is coalition collapse, followed by a CDU minority government reliant on shifting parliamentary majorities. The third is a formal confidence vote under Article 68 of the Basic Law, the German constitution, which, if lost, could trigger early federal elections before the scheduled 2029 date.

Each option is constrained by the crisis that makes it seem necessary. A "Kanzlertausch” requires a successor willing to step forward. Wüst has made no such move. It also risks the emergence of a panicked internal coup. Coalition collapse could hand the AfD a decisive advantage in a snap election fought under current conditions, as Söder and Kretschmer have both warned. The paradox of the present moment is precise: The case for replacing Merz is clear, but the institutional cost of doing so is high enough to deter every actor positioned to act, producing a fragile equilibrium that could hold or collapse with little warning.

Merz entered office in May 2025 with a mandate to reverse Germany’s economic stagnation, contain the far right, and restore the CDU as the central force in federal politics. Sixteen months later, the AfD leads national polls, the CDU holds no seats in Mecklenburg-Vorpommern for the first time since reunification, and only 14% of Germans regard him as the right person for the office. His own minister-presidents have issued declarations of solidarity that conspicuously omit his name.

The autumn of 2026 has demonstrated that the formal authority of the chancellorship and the political power required to exercise it have become decoupled. The "Kanzlerdämmerung” is no longer a metaphor, but it is an accurate description of the present moment. Whether Merz survives, is replaced through internal negotiation, or leads the coalition to collapse, the conditions he leaves behind will shape German politics for years to come.
