The clearest sign Germany’s “firewall” against the far right no longer means what it says came four days after Saxony-Anhalt voted. BSW co-chair Amira Mohamed Ali, holding the balance of power with just 5.3% of the vote, did not propose blocking the AfD by rallying the other parties behind the incumbent CDU premier. She proposed a “nonpartisan” premier instead — someone from neither camp, who would then govern with AfD votes in the chamber alongside her own. The AfD’s candidate rejected the idea. But nobody on the anti-AfD side rejected the underlying logic: that keeping the AfD out of the premier’s office while accepting its votes to govern is a different thing from keeping the AfD out of power. It only sounds different.
On September 6th, the AfD won Saxony-Anhalt with 43.8% of the vote — a state the CDU had governed for 24 years, reduced overnight to 17.2%. Turnout hit 77.8%, exceptional for a state election. The result put the AfD one seat short of an outright majority if paired with BSW, the only other party willing to deal with it. This was not supposed to be a live scenario. Germany’s postwar consensus holds that no mainstream party forms a coalition with, or accepts votes from, a party the domestic intelligence service classifies as extremist — the Brandmauer, or firewall. It survived a similar stress test in Thuringia in 2024, when the AfD also won the most votes and an ideologically incoherent multi-party coalition formed anyway, purely to keep it out. Saxony-Anhalt is the same test, run again, with a much larger AfD and a much weaker CDU.
The honest answer to whether the firewall held in Thuringia and is holding now is: only in the sense that matters least.
Start with the precedent that made this thinkable at the national level. In January 2025, Friedrich Merz’s CDU brought a non-binding Bundestag motion on migration to a vote knowing it would only pass with AfD support — and it did, in what the AfD itself called a historic moment, the first time since 1949 that a Bundestag majority had been assembled with the far right’s votes on a significant question. The follow-up bill, binding this time, failed two days later after CDU and FDP defections amid mass street protests and a public rebuke from Angela Merkel. Merz’s team calls the episode closed. But the fact pattern — a mainstream party accepting AfD votes to win, then insisting the acceptance doesn’t count because the specific bill later failed — is exactly the template BSW is now running in Magdeburg with a “nonpartisan” premier who would govern on AfD votes without being of the AfD. The mechanism has already been normalized. Only the packaging changes.

The Thuringia comparison cuts the same way. Mainstream parties did keep the AfD out of the premiership there in 2024, and that is real. But they needed a coalition spanning the CDU, the Left party’s BSW splinter, and other partners with little in common beyond not being the AfD — a construction explicitly built for one purpose and expected to be unstable. A firewall that requires an ideologically incoherent emergency coalition to function is not a firewall in the sense Germans mean when they invoke the word: a broad democratic consensus that the far right is illegitimate. It is closer to a temporary parliamentary maneuver, renewed each time under worse arithmetic. Saxony-Anhalt’s numbers are worse than Thuringia’s. The AfD is bigger, the CDU is smaller, and BSW — this time the pivotal actor — is explicitly open to “issue-based collaboration” with the AfD, which is not a sentence anyone could have said about a firewall party in 2020.
The counter-argument deserves a direct answer, because Merz and his allies will keep making it: no CDU, SPD, Green or Left leader has actually put an AfD politician in a premier’s chair, and by that literal standard, the firewall is intact everywhere in Germany. That is true and it is also the weakest possible definition of success. AfD’s own Ulrich Siegmund is not treating the firewall as an unbridgeable norm — he has said he may try to persuade individual lawmakers from other parties to defect and hand him a majority directly, a mechanism, not a hope, that plays out over the 30 days Saxony-Anhalt’s parties now have before the new parliament convenes on October 6th. A party leader planning to route around a norm by buying it off one defector at a time is describing a norm he expects to break, not one he respects. The question worth asking is not whether the firewall’s language survives — it will, in every press conference — but whether it is still doing the work language is supposed to do, which is constraining behavior before the fact rather than being renegotiated after every election.
The federal stakes make this more than a Magdeburg story. Merz’s own approval sits at levels no postwar chancellor has matched, by his own AfD rival Alice Weidel’s telling, and his CDU-SPD coalition already governs without enthusiasm from either side of it. A CDU that just lost half its support in a state it ran for a generation is not a CDU with room to relitigate the firewall question calmly before 2029. Every regional collapse of this kind pushes the party toward the same two bad options: hold the line and keep losing ground to the AfD’s growing plurality, or start finding “nonpartisan” and “issue-based” formulas of its own to blunt the bleeding — the precise slope Saxony-Anhalt’s BSW just demonstrated. Neither path is a firewall holding. Both are a firewall being managed on the way down.
What Happens Next
Three ways the next 30 days play out, and the mechanism behind each matters more than the headline.
Base case (55%): A multi-party “anything but AfD” coalition forms in Magdeburg, Thuringia-style, built from the CDU, SPD, Greens and Left despite having little programmatic agreement — or BSW’s nonpartisan-premier idea gets a second look once its current form is rejected. Either way, Saxony-Anhalt gets a government that can block the AfD from the premiership but struggles to pass a budget or govern with any mandate, which is precisely the weak, reactive outcome that let the AfD grow from roughly 20% to 43.8% since the last election.
Downside case (25%): Siegmund’s defection strategy works. A handful of CDU or BSW state lawmakers, facing a party base that already voted AfD in large numbers, cross the floor or abstain at the decisive moment, handing the AfD the one seat it needs. This would make Saxony-Anhalt the first state led by a far-right party since 1949 — a specific, mechanical outcome (individual defections, not a mass realignment) that hinges on names and votes traceable in the 30-day window, not a vague drift rightward.
Upside case (20%): The scale of the Saxony-Anhalt shock forces Merz to recommit the CDU to the firewall explicitly and unconditionally at the federal level, reversing the ambiguity opened by the January 2025 migration vote, in exchange for SPD concessions that stabilize his coalition through 2029. This would cost Merz real political capital he has shown little appetite to spend so far, which is why it is the least likely of the three — but it is the only path that treats the firewall as a principle to be restated rather than a formula to be re-engineered.
These probabilities reflect the author’s analytical judgment based on currently available information, not a statistical forecast.
Saxony-Anhalt did not test whether Germany’s firewall against the far right would hold. It tested whether anyone still treats it as a political conviction rather than a set of workarounds to be renegotiated after every AfD advance — and the answer, from a BSW leader inventing a “nonpartisan premier” within days of the result, is no. The firewall’s language will survive this news cycle intact, as it always does. Its function is what is eroding, one procedural formula at a time.
Watch for: what actually gets voted on before Saxony-Anhalt’s parliament convenes on October 6th. A conventional multi-party coalition that excludes the AfD outright would mean the firewall bent but held. Any arrangement resembling BSW’s nonpartisan-premier formula — or a defection that hands Siegmund his majority directly — would mean it has already given way, and Magdeburg was simply where that became visible first.
