Müller was chancellor only until June 1920, when the outcome of the general elections to the Reichstag resulted in the formation of a new government led by Constantin Fehrenbach of the Zentrum. The SPD suffered a defeat at the polls, with the number of people voting for them almost dropping by half compared to the January 1919 election. Discouraged, Müller only half-heartedly negotiated with the USPD about a coalition. However, he was turned down anyway, as the USPD was unwilling to join any coalition including non-socialist parties and one in which the USPD was not the majority party. On the other side of the political spectrum, Müller was opposed to working with Gustav Stresemann's German People's Party (DVP), considering them a mouthpiece for corporate interests and doubting their loyalty to the republican constitution.
