I believe that Schmitt believes liberalism can't make the friend enemy distinction, as a result of the state being pluralistic and influenced by multiple groups. Since there are multiple groups, there are multiple identifications of who the friends and enemies are, and many of these identifications of which conflict, resulting in a blurred image of friends and enemies. In this situation the center point is the constitution but the ruling party(s) of the state.
