The Berlin airport fiasco was absolutely on the left-wing government.

hehehe, this made me chuckle. 25 years of hard-core socialists running the show, and all of a sudden its the conservatives that ruined Berlin. that is rich. It's even funnier when considering the Länderfinanzausgleich (Equalization payments between federal states): Basically within those 25 years Berlin, under those financially savvy and responsible leftists, amassed 95 B € in payments from all other German Federal States.
