Kai Wegner is out as Berlin's CDU chief, and the succession question is already answered: Stefan Evers is taking over. Our earlier piece covered the resignation itself and the immediate embarrassment it caused Merz; what's new is who picks up the pieces, and what the latest national polling says about how much room he has to work with.
Who is cleaning up, and how bad is the mess?
Evers steps into what Pascal Biedenweg of the Berliner Morgenpost's editorial leadership calls a genuinely difficult starting position, telling Welt that the coming campaign will need to shift back toward substance rather than the personal drama that dominated Wegner's exit. That framing matters: Berlin's CDU now has to fight a state election campaign defined less by what it wants to do in government and more by why its last leader had to go.
What does the national polling say?
The timing puts Evers under a spotlight the local party didn't choose. The latest Insa Sunday poll, reported by Welt, shows the Union narrowing its gap to the AfD slightly. That sounds like relief for the party. It isn't, once you look at the second number in the same poll: approval for Chancellor Merz personally, and for his government as a whole, remains stuck at very low levels. A party can gain a point or two on its main rival while its own chancellor stays deeply unpopular — those are two different trend lines, and right now they're pointing in different directions.
That gap between party and chancellor is exactly the problem Berlin's CDU can't fix on its own. Evers can run the most disciplined, policy-focused campaign imaginable, and it will still be read nationally through the lens of whether Merz's coalition can turn around the numbers that matter most: his own.
Why the AfD's spread makes this different from past dips
The instinct inside establishment parties has long been to treat the AfD as a protest vote that peaks and recedes, containable through isolation. A Welt analysis by Harald Martenstein argues that instinct no longer matches reality: the AfD has grown to the point where it is represented across nearly every social milieu and almost every region of the country, per Welt. The piece's core argument is that treating the AfD as a fringe phenomenon that can still be shrunk back through demonization is out of step with how broadly it has actually spread.
If that reading holds, Berlin's leadership churn is a symptom of a bigger shift rather than a one-off scandal. A party that has embedded itself across milieus and regions isn't dislodged by one rival's better messaging in one city-state election — it requires the governing coalition itself to look competent and popular, which is precisely what Merz's numbers currently aren't delivering.
HYPOTHESIS: Berlin becomes the test case for Merz's coalition strategy at the EU level
Hypothesis: how Evers performs in Berlin will shape whether Merz's CDU doubles down on firm-cordon coalition politics against the AfD or faces internal pressure to soften that line, with consequences for how Berlin behaves in EU Council negotiations and transatlantic coordination on issues like Ukraine funding and tariffs. Supporting this: the source material shows the Union's national approval stuck low even as it narrows the AfD gap, meaning the pressure for a different strategy is structural, not tied to one bad news cycle, and the milieu-spread argument suggests the AfD is no longer easy to contain through exclusion alone. Against this: none of the three sources address EU or coalition strategy directly, and a single city-state leadership change is a thin basis for predicting shifts in Berlin's European or transatlantic posture — the connection here is inference, not reporting.
What to watch next
- Whether Evers can shift Berlin's campaign coverage from personnel drama to policy, as Biedenweg says is the goal
- Subsequent Insa or other pollster releases, to see whether the Union's narrowed gap to the AfD is a trend or a one-week blip
- Whether Merz's personal approval moves independently of his party's numbers, or continues to lag behind
- Any signs that the AfD's milieu-spread, as described by Martenstein, is prompting CDU figures to publicly debate the containment strategy
