Surveys indicate the Alternative for Germany is the nation's most popular party with 28% support. The electoral outcome prompted international and domestic reactions, including Polish Prime Minister Donald Tusk stating that "only idiots and traitors can rejoice at the triumph of the AfD." US President Donald Trump and Russian envoy Kirill Dmitriev also reacted to the vote. Merz accused the party in the Bundestag of advocating "ethnic cleansing" based on origin and skin color through its remigration policy, warning that the approach would severely impact Germany's workforce, specifically skilled trades, nursing homes, hospitals, and restaurants.

Germany's domestic security agency classifies the Saxony-Anhalt branch of the party as right-wing extremist, a label the organization rejects as politically motivated. The platform includes strict immigration restrictions, deportations, removing the euro, and reducing Holocaust education. Professor Lars Rensmann stated that the party has "systematically embedded antisemitism into its core ideology." Josef Schuster, president of the Central Council of Jews in Germany, urged a boycott, calling the group a "declared enemy of our open society." A firewall of mainstream parties, supported by the domestic intelligence agency, currently prevents the party from governing.
