Well, it would only be fair, Stoiber always sits next to Merkel, so they have to be treated as two parties. They made a contract with each other not to compeat in each others territory, but I know they used to try and also the CSU got mightly burned, when they tried to establish the DSU after the Wende. One of my professors was a founding member of the DSU, it was very interesting...
So Parties or Factions? Big question.
But I don't think, it has sunk through to everybody yet, it might still be just a theoretical one.
But still, despite the DSU-story, Schröder can't get around the fact that CDU and CSU are not competing.
However, the two-parties-argument is nothing but a formal legitimation for Schröder to do what he will do anyway: Trying to build a coalition.
If the CSU is not represented in all the Bundeslaender, what kind of legal consequences does that have?
Completely confused. What a mess all that.
