Sarko and the UMP won a majority. Are Libe and Le Monde to the left of Sarko - I'd say yes, with Libe well to the left. Le Monde's views dovetail with the right wing of the PS - i.e. it is center-left. Libe's views tend to be those of the middle and left of the PS, i.e. it is left.

You can argue that the right wing of the PS is really center-right. However, you then also have to accept that the French electorate tilts sharply right and simply doesn't want left wing policies.
