As you say, the media don't count any of this as the least false note in Sarko's campaign. There are no false notes in Sarko's campaign.
This morning on France Inter, journalists Roland Mihail and Pierre Weil mocked François Hollande when he called for Socialists to unite in support of SR: Is that a cry of "Help!"?
I'm not a betting man, and I have no idea of what may happen. But I have the feeling that Sarko is a bit too close to overweening pride at the moment, and that this one-way media narrative will end up by being too obvious. Turning-point soon?
