Well, fortunately, the Realo wing in the Green Party still consists of a lot of dreamers, so much is evident from the manifesto.  And if you look at what they have achieved (or tried to achive) in the last 7 years, they realized some of the dreams.  Ie, exiting nuclear energy, a new citizenship law, an eco-levy on energy, strong consumer protection laws and so on.  I'm a bit disappointed that there are so few specifics in the manifesto, I'll have to take a look at their web site to find out more details about their proposals.

The problem with the Greens is that they fail to inspire anybody that is not already voting for them.  They are also very much a western party, except for Berlin they have a very weak showing in the east.  Maybe they should work more on the local level (like the PDS in the east) to draw more people towards them.
