The thing is that he is not a moron, but a corrupt a**hole. You can be sure that he is paid off well by Gasprom (he will not work for them directly but indirect through their vassals Wintershall and Eon) after his lost election for doing absolutely nothing. It is not bad to get - lets say 1.000.000,- Euros/year - for passing gas into an armchair. He knows very well that his political career is toasted.
Anyway there is another problem:
Merkel will get chancellor, but her vice chancellor (and foreign minister) is going to be probably Peer Steinbrück from the SPD, since the FDP will not have enough votes to form a coalition with the CDU. The good news are, that Steinbrück is not homosexual (im comparison to the chairman of the FDP, Westerwelle), but under his influence the current German foreing policy will continue to a certain extend in the future. Steinbrück is different to Schröder, but he also sees things different than Merkel. It will stay interesting.
Take a look at my #7
So Gazprom will have interesting "managers" in the future! Kwasniewski, Miller (Leszek not Alexey! Btw family? Maybe maybe :)) and now Schroeder. Who next?
