What’s Happening

The Berlin state election, scheduled for September 20, 2026, is emerging as a critical test of Germany’s post-war political firewall, with the far-right Alternative für Deutschland (AfD) polling in second place in the capital. While the AfD’s strongest performance is expected in eastern states like Saxony-Anhalt—where it leads with 42 percent support ahead of the September 6 vote—the party’s trajectory in Berlin has shifted the national conversation. A recent Sunday poll from early August shows the AfD extending its lead in nationwide surveys, and internal party strategists have publicly targeted the Berlin election as a winnable contest, despite the city’s historically liberal electorate. The question of whether the AfD can win the most seats in the Berlin state elections remains a long-shot scenario, but the party’s second-place standing has forced mainstream parties to confront the possibility of a fragmented parliament where coalition math becomes untenable [DW, Aug 07].

The procedural stakes are unusually high because of the “firewall” doctrine—the informal agreement among established parties to refuse any coalition or confidence-and-supply arrangement with the AfD. In Saxony-Anhalt, the AfD is poised to win the most votes on September 6, and if it secures an absolute majority of seats, it would become the first far-right party to govern a German state since 1945, granting it access to state-level intelligence briefings and security appointments. That outcome, according to reporting from Berlin, has prompted government leaders across Germany to explore legal and administrative measures to limit the party’s access to sensitive information, even if it wins. The Berlin election, occurring two weeks later, is now viewed as a bellwether: if the AfD can translate its second-place polling into a strong seat count in the capital, it would signal that the party’s appeal has moved beyond the former East Germany and into urban centers, making the “afd most seats in the berlin state elections” scenario less hypothetical than previously assumed [NYT, Aug 30].

Chancellor Friedrich Merz’s Christian Democratic Union (CDU) is facing a dual crisis: its support in Saxony-Anhalt has collapsed to roughly half of the AfD’s numbers, and its coalition partner, the Social Democrats (SPD), is polling barely above the 5 percent threshold in several eastern states. The Greens are also hovering near that threshold in Berlin, raising the possibility that the next state government could require a three- or four-party coalition, a scenario that historically depresses voter turnout and benefits insurgent parties. The AfD’s national polling lead, which it has held since April 2025, has not translated into a Berlin majority, but the party’s ability to force the “afd most seats in the berlin state elections” question into public discourse has already had an effect: more voters now say they support including the AfD in decision-making on a case-by-case basis, a shift that undermines the firewall’s legitimacy. With the Berlin vote now less than three weeks away, the CDU and SPD are expected to finalize their candidate lists and campaign strategies this week, while the AfD is holding rallies in districts where it saw the largest gains in the 2021 federal election [Guardian, Aug 19].
