Anectodally, the two piles (out of the 12) of paper bulletins for the candidates which had the most bulletins taken from them were very clearly Sarkozy AND Royal. I went to another polling area with my neighbor, there it was Sarkozy ahead, with de Villiers and Royal follwing further behind.
That's only the bulletins that people take before actually choosing - and note of course that this is the 16th arrondissement, i.e. posh and conservative (for the most part). In the long run, we're all dead. John Maynard Keynes
