Frankly there are no way for Royal to win (If Sarko does not make a big mistake) and the likely strategy for her, is to keep her left to keep the PS alive for the legislatives election (parlement, She still need the extrem left to win a large part of the PS' paliamentary seats and cannot affraid them by being too center)

Unfortunately for some, with the end of the extrem-right the left has not more possibility to get back and win another election :

Lepen has been a precious ally for the left to win the parliamentary seats.

Sarko will be president for 10 years, since presidents are usually reelected and UMP will stay in power much longer.

I hope they will create a shadow minister.
