Yup, really old, and h's getting quite senile. As you said, her daughter isn't popular at all. She was at the head of FN's list for regional elections in 2004 (she presented herself in Ile de France, Paris' area), and she did FN's worst score in IDF since its creation, in the 70s (less than 10%, while ordinary it is 13-14%). I think it will be Bruno Gollnisch in 2012 (see
http://en.wikipedia.org/wiki/Bruno_Gollnisch)
It would be a good thing if he's a candidate. "L'agité du Bocage" is always taking votes from Le Pen.
Chirac won't run. He's said to be depressed and deaf. Not really good for a candidate, no more for a president. French people use to love Galouzeau de Villepin (his real name in fact, and Sarkozy's real name is Sarkozy de Nagy-Bocsa. Really crazy.) since his fight with wolin Powell, when he defended France interests. He's I think as popular as Sarkozy, who did some blunders weeks ago.
I d'like to have for the second round something like De Villepin/Strauss-Khan or De Villepin/Lang. But not Sarkozy, nor does Le Pen.
