The Left itself had been neutralized after the demise of the two socialist states, and in such a way that there continued to be bad blood between the Communist Party (KPD) and the Social Democratic Party (SPD) that prevented them from working together throughout Germany. This lack of cooperation, with the Communists seeing the Social Democrats as betrayers of the Revolution, and the Social Democrats seeing the Communists as under the control of Moscow, was later to rebound to the advantage of the Nazi Party, since only a parliamentary coalition of the KPD and SPD could have prevented the Nazis from coming to power. Even at the height of their influence in the Reichstag, they did not have enough delegates to resist such a coalition.[20]
