I don´t agree, anecdote wise. I talked with my mother - she is well into the over 65 category - about the acceptance of Segolene by her friends who are mostly women over 65 and among them a lot rural and/or deeply catholics women and she told me that some of them were mentioning the kids out of wedlock.
She confirm the statistic of the poll, and told me she had some heated argument when saying around  she was prone to vote Segolene.

La répartie est dans l'escalier. Elle revient de suite.
