I often mention the case of Spanish women majoritarily opposing women's suffrage in the 1930's when the Second Spanish Republic gave them the vote, and going on to vote for the right-wing at the next election.

There are two reasons for this: one the acceptance by women of the social gender norms that it was not for women to take part in decisions in the public sphere; and the other a stronger propensity by women to follow what the Cathilic priests said in their weekly holilies.

Some of the same might be at play here. Including what someone mentioned of not letting a younger woman (Segolene is 53) become the "alpha female" in the matriarchy.

Bush is a symptom, not the disease.
