        Why Forming a Government is Difficult in Post-Election Germany
      

      

        

          The Cordon Sanitaire ("Brandmauer"):
          
Mainstream conservative (CDU), center-left (SPD), and green parties maintain a firm policy pledge against forming state or federal coalitions with Alternative for Germany (AfD), classifying it as an extremist threat.

        

        

          The Blocking Minority (Sperrminorität):
          
When a single party reaches over 33.3% of the seats (1/3rd), it can unilaterally block two-thirds majority votes required to appoint regional constitutional judges or amend state constitutions.

        

        

          Ideological Strain with BSW:
          
Excluding AfD requires traditional center-right parties (CDU) to ally with left-populist Sahra Wagenknecht Alliance (BSW), creating high ideological friction over foreign policy and welfare spending.
