1. The Left Party doesn't make it across the 5% limit. Then it can only be one block or another:

• 1.A CDU+FDP has (narrow) majority: looking at polls, almost certain
  
• 1.B SPD+Greens have (narrow) majority

• 2.A SPD+Greens+Left Party: Ypsilanti declared it impossible, nor would the rest of SPD tolerate it, and methinks the Left Party realises it would be a death kiss for them
  
• 2.B Traffic lights coalition (SPD[red]+FDP[yellow]+Greens): I don't think many social-liberals remained to sustain that, and the Hessen FDP recently declared they won't coalition with "this SPD"
  
• 2.C Grand Coalition (SPD+CDU): is a possibility if the CDU gets rid of Koch. But Merkel recently declared no Grand Coalition in Hessen. Then agai, shafting voters on both sides, a Grand Coalition without both Koch and Ypsilanti is a possibility.
  
• 2.D SPD+Greens minority government with Left Party support: not much more comfortable for all involved than 2.A, yet probably the most likely
  
• 2.E new elections: who would want it?
