AfD takes 43.8 percent in Saxony-Anhalt and falls three seats short of a majority

Alternative for Germany won 43.8 percent of the vote in Saxony-Anhalt on 6 September, more than double its 2021 share, and took 39 of 83 seats in the Magdeburg legislature. That is three short of a majority. Chancellor Friedrich Merz's Christian Democrats fell to 17.2 percent and 15 seats, their worst result in a state they had led for 24 years. About 83,000 former CDU voters moved to the AfD. Merz said the outcome "shakes our party to its very foundations" and later called it his party's worst election result in decades. He ruled out working with the AfD and said he would not resign.

State AfD leader Ulrich Siegmund said the party had a mandate to govern and would not play "games" such as a minority cabinet. National co-leader Tino Chrupalla told ARD that politics means compromise and asked CDU deputies to make a "centre-right conservative majority" possible. Co-leader Alice Weidel called the night historic. Chrupalla also turned Merz's old pledge back on him: "We've cut the CDU in half."

The arithmetic now sits on the firewall, the unwritten rule that mainstream parties do not govern with the AfD. Siegmund wants that rule broken in Magdeburg, either by a formal coalition or by individual CDU votes. The AfD programme in the state includes a harder line on deportations, separate school classes for refugee children, limits on Islamic public expression, an end to support for Ukraine and warmer ties with Moscow. France and Poland both called the result a warning. Polish foreign minister Radoslaw Sikorski described it as "a very worrying sign."

The local campaign was national. An ARD poll found 87 percent of Saxony-Anhalt voters were unhappy with the federal government. CDU candidate Sven Schulze blamed Berlin. Economist Marcel Fratzscher called the vote a no-confidence verdict on the coalition. Merz's personal ratings are the lowest recorded for a postwar chancellor. He said he would stick with his reform agenda and try harder to reach voters. Thorsten Frei, the CDU/CSU group leader in the Bundestag, called the night a "turning point for our country." Sahra Wagenknecht of the BSW said another coalition built only to exclude the AfD would be an affront to the people who voted.

Saxony-Anhalt has 2.1 million residents and sits west of Berlin. It is the first eastern state in this cycle to put a far-right party this close to the state chancellery. The AfD does not have 42 seats. No other party has offered it the three it needs. That is the entire government-formation problem. If the CDU holds the firewall, Magdeburg has to assemble a cabinet from the remaining 44 seats, a bloc that lost the election and may not agree on a minister-president. If even a handful of conservative deputies peel off, Siegmund becomes the first AfD head of a German state since 1945.

Merz has days, not months, before that choice becomes visible. Coalition math in a small legislature is public. Each CDU deputy who refuses a call from Chrupalla is a recorded fact. Each deputy who takes the call is a recorded fact. The firewall is no longer a speech. It is a headcount in Magdeburg.
