I'm sure of nothing. It's a possibility. Sarkozy is now a very unpopular president and people has a lot of reasons not to vote for him. Strauss-Khan is the only socialist who today has an image of economical and international competence. Soialist will necessarily have to chose a candidate, and they have interst to take the best one. Copé has the political craftiness and cynism of Sarkozy. If Sarkozy hates him, it's because he knows that when he will want to take his place, he will treat him as Sarkozy treated Chirac.
Anyways, where are your own lists ?
The truth is I'm not a big expert in French politics and for an expert it would be virtually impossible to succeed in predicting the next two presidents but I'll have a go at it.
I think that Sarko will survive his reelection bid in 2012, in 2017 a petty UMP politician will succeed him and in 2022 the socialists will rise.
Who will they be? I don't know, maybe a current minister in Fillon's government (what about Lagarde? Morin?) or a current mayor or, most likely, a current nobody.
Thank you Hashemite, you would be consider a centrist in french politics, wouldn't you?
