Actually, it isn´t the media insulting the "renegade", they´re just reporting what the Left says. Treason depends on the viewpoint. Imagine the same situation just with the CDU/FDP in the place of the SPD/Greens with a Christian Democrat refusing to accept the "Danish coalition" - Mr Müntefering and all the others had praised this great MP for showing morale!
I find it pretty much undemocratic to insult this person. He/she in no way "abused" the secrecy of the election. This is why we have it: nobody shall be offended, attacked, insulted for his/her vote. This IS democracy, and who doesn´t accept it, may harbour ill against the rebel, but must not blame him for following his/her free will.
It was good to see that Carstensen said no compromises in school reform in the case of a grand coalition. It looks like he's telling Anke Spoorendonk where the exit doorway is located. I think the school reform issue was more important than people realized.
