How much has their position shifted over the last forty years?
To what extent do they influence and define policy compared for the FT, the Econo and the WSJ? (Even in France.)
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.
Libe aims for the right wing of the PS, nowadays (for example they were for the Yes in the Constitution referendum). This has changed in the last few years. They are anti-Sarkozy, but increasingly (Euro-)liberal in their economics commentary. They are center left at best, in their current incarnation.
As for the French electorate - the 2007 presidential election represents the French opinion badly, as on the left it was skewed by the need to have somebody from the left in the second round. In 2002, and in various regional elections, people calling themselves Communist gathered 15% of the vote, with other parts of the left, like the Greens, getting another 10%... And the right wing of the PS has pretty much joined Sarko. The PS has bee to the right of its electorate for quite some time. Un roi sans divertissement est un homme plein de misères
Unless you think anything to the right of Olivier Besancenot does not belong to the Left... "Dieu se rit des hommes qui se plaignent des conséquences alors qu'ils en chérissent les causes" Jacques-Bénigne Bossuet
But it is true that left narratives can be found in Le Monde and Libération, although they are not necessarily prevalent. After all, Jérôme was published there... Un roi sans divertissement est un homme plein de misères
