Can Germany’s Firewall Survive a 42% AfD Vote?

The AfD holds a 20-point polling lead in Saxony-Anhalt. Yet the state’s next government may be decided by parties hovering around 5% and by what happens after the ballots are counted.

A party can finish first by 20 percentage points and still fail to take office. Saxony-Anhalt may soon show Germany how.

The eastern state votes on September 6. A late-August Infratest dimap survey puts the Alternative for Germany (AfD) at 42%, far ahead of the governing Christian Democratic Union at 22%. The Left follows on 11%, the Social Democrats on 8% and the Greens on 6%. The BSW and Free Democrats remain below the 5% threshold required to enter the state parliament.

That looks like an overwhelming AfD victory. It is not necessarily an AfD government.

The election contains three separate questions.

1. Which party receives the most votes?
2. Does any party control a majority of seats?
3. Can someone assemble enough parliamentary support to elect a minister-president?

The AfD is strongly favored on the first. The other two remain open.

The Number to Watch Is 5%, Not 42%

Votes cast for parties that fail to clear the 5% threshold are largely excluded when proportional seats are distributed. That can turn a large plurality into a parliamentary majority without the party winning half of the popular vote.

Using the latest poll as a simplified illustration, the five parties currently above the threshold account for 89% of the vote. The AfD’s 42% would therefore translate into roughly 47% of the votes represented in parliament not enough to govern alone.

However, if move the Greens from 6% to just below 5%, the represented vote will falls to roughly 83%. The AfD’s unchanged 42% would then amount to slightly more than half of that total.

Actual seat allocation will also depend on constituency results and the final distribution of votes. The calculation nevertheless explains why the parties near 5% may be more important to government formation than another one- or two-point change in the AfD’s headline number. Reuters (30 Aug.) similarly assessed that 42% would probably leave the party just short of a majority, with the smaller parties determining whether that remains true. 

It has also produced an unusual tactical-voting campaign. Some anti-AfD groups are encouraging voters to support the SPD or Greens—not necessarily because they are their first choices, but because keeping those parties above 5% expands the non-AfD side of the parliament. 

A Firewall Can Block Power Without Producing a Government

Every major party has ruled out a coalition with the AfD. That commitment, known as Germany’s political “firewall,” has kept the party out of every state and federal government despite its growing vote share.

A plurality would not break the firewall by itself. An outright majority would.

Anything between those outcomes creates a much less comfortable test. Under the latest poll, the CDU, SPD and Greens together have only 36%, which is six points less than the AfD. Add the Left and the anti-AfD side reaches 47% but Chancellor Friedrich Merz has repeatedly ruled out CDU cooperation with both the AfD and the Left.

The available options could therefore include a broad coalition that crosses old ideological boundaries, a CDU-led minority government relying on outside support, or a prolonged attempt to negotiate a workable arrangement. Each would preserve the firewall but none would look particularly stable.

Even falling short of a parliamentary majority would not make the minister-president vote irrelevant. Saxony-Anhalt initially requires a candidate to win the support of a majority of all Landtag members. If two ballots fail, parliament must consider an early election. Should it reject dissolution, a later ballot can be won with a majority of the votes actually cast. Absences, abstentions and coordination among AfD opponents could therefore become decisive. 

The firewall is consequently more than a promise not to sign a coalition agreement. The other parties must cooperate sufficiently to elect and sustain an alternative government.

The AfD Is Selling More Than an Immigration Policy

It would be easy to explain the AfD’s lead entirely through immigration. That would miss much of what has made its campaign effective in Saxony-Anhalt.

The party has connected migration, energy prices and distrust of Berlin to a broader story about eastern German identity. At one rally, nearly 5,000 people attended an event centered on Simson motorcycles, a brand closely associated with life in the former East Germany. Among the state’s voters aged roughly 18 to 34, AfD support in the 2025 federal election reached about 40%, up from approximately 25% in 2021. Nostalgia is being passed to voters who did not personally live under the German Democratic Republic. 

Material disparities reinforce that appeal. Unemployment in Saxony-Anhalt peaked at 22% in 2003 and is now around 8%, yet people in eastern Germany still hold only about one quarter of the wealth of western Germans. The economic upheaval following reunification remains part of the region’s political memory.

The AfD has folded Russia into the same argument. Its state program calls for better relations with Moscow, an end to sanctions and reduced German support for Ukraine. It also evokes the cheap Russian energy that once supported German industry.

Those promises collide with a new security dispute. Germany has blamed Russian state actors for an attempted drone attack at Leipzig/Halle Airport, close to Saxony-Anhalt, while Moscow has rejected the allegation. Berlin is now pushing for additional European sanctions just as the AfD campaigns for the opposite policy.

A state government cannot independently lift EU sanctions, restore national energy agreements or end Berlin’s support for Ukraine. The AfD is therefore asking voters to use a regional election to reject policies largely decided elsewhere—a strategy that can win votes even when the state itself lacks the authority to deliver the central promise.

The Candidate Makes the Experiment Look Less Experimental

Ulrich Siegmund, the AfD’s 35-year-old lead candidate, has presented a friendlier public image than some of the party’s better-known figures. He avoids much of their harsher rhetoric, campaigns heavily through social media and speaks about renewal, affordability and local pride.

That presentation sits alongside a more serious institutional dispute. Saxony-Anhalt’s domestic intelligence agency classifies the state AfD organization as belonging to the extremist far right and as hostile to Germany’s democratic order. Siegmund rejects both the label and the accusations behind it.

The contrast is central to his appeal: a radical change in government delivered through a candidate who does not look or sound especially disruptive.

Merz has tried to raise the cost of that choice. He warned that international companies could avoid investing in a state led by an AfD minister-president. For now, that is a political risk argument rather than a measured economic result. No AfD-led state government has existed to provide a German comparison. 

Investors will nevertheless be watching how an AfD administration approaches public appointments, skilled immigration, education, energy policy and the state bureaucracy. The signal may reach beyond Saxony-Anhalt even before any policy changes.

A Victory With Three Different Meanings

The AfD already describes Saxony-Anhalt as the first step toward federal power in 2029. It was polling at 27% nationally in late August, five points ahead of the CDU/CSU in one Politbarometer survey, while Berlin and Mecklenburg-Western Pomerania are also due to hold state elections on September 20. 

Yet September 6 may produce several kinds of victory.

Finishing first would confirm that the AfD can dominate an eastern German election. Winning a majority of seats would give it a direct path to Germany’s first far-right-led state government of the postwar era. Falling short but leaving its opponents dependent on a fragile minority arrangement would produce something less visible but still valuable to the party: evidence for its argument that the existing system can exclude it only by becoming harder to govern.

The largest number on election night will be 42%, or something close to it. The numbers that decide who takes office may be much smaller.
