After the April 1946 merger of the German Communist Party [Kommunistische Partei Deutschlands or KDP] and the Eastern SPD, the newly formed SED expected a clear majority in the communal, regional, and state elections scheduled for September and October, 1946, in the Soviet occupation zone. Massive discrimination against the bourgeois parties CDU and LPDP helped the SED win 58% of the vote in the communal elections, and slightly more than 50% percent in the regional assembly elections, but it failed to secure an absolute majority in the state parliament [Landtag] elections. The SED's performance was particularly disastrous in Berlin, where the SPD still ran for election independently: the SED received only 19.8% of the vote and thus trailed the Eastern CDU, while the SPD received almost 49% of the vote, clearly winning the election.
Below is an SED poster for the elections in the province of Saxony. It reads: "Your Vote for the Socialist Unity Party for Reconstruction, Peace, Work, and Bread!"
