Moreover, I don't claim that Wowereit will become the SPD's nominee at any rate, I just say that his chances have risen tremendously since his reelection.
This was his worst election result since 2001. He was re-elected as expected, but not as strong as expected. The fact that the Greens also failed to meet expectations doesn't change that.
So I fail to see how this risis his chances "tremendously". His chances are the same as before the election, maybe even a little lower.
His government was voted out....and his prefered coalition has a majority of 2 seats. I can't see how this improves his chances for anything. Except being able to continue as Mayor of Berlin.
