Franks electing a Jew to be their president? I'd like to see that phenomenon. Doesn't Kahn "fail to have the face of rural [real!] France?"
It's been done, sort of Leon Blum was President of the Council of Ministers three times. However, this was essentially a Prime Minister ship. He was also President of the provisional government after World War 2.
Blum was a socialist na dfairly incompetent, although the Third Republic was unmanageable with governemnts lasting months. I give Blum credit for his actions during World War 2, in trying to stop the communists from sabotaging the war effort. He could have fled Vichy France. Instead he stayed, and voted against giving power to the traitor Petain. He was later arrested and prosecuted by the Vichy courts along with other Third Republic officials for failing to protect France. Blum made such a fool of the prosecution that the Vichy regime and Nazis called off the trial. Blum was then sent to Buchenwald.
Strauss-Kahn isn't fit to clean Blum's memorial.
