During his decades in exile, Ghannouchi wrote extensively about the compatibility of Islam and democracy, and developed a relatively liberal vision of how Islam and the state should interact. Skeptics then claimed that Ghannouchi’s views were a cover for a more radical agenda; and some Tunisian secularists still think so. But the evidence thus far is sharply to the contrary. When Islamists called for inserting a reference to Shariah into the Tunisian constitution -- usually the sine qua non for any Islamic political party -- Ghannouchi took seriously the opposition from secularists. In a dramatic showdown with members of his own party’s leadership, he reportedly threatened to resign unless they dropped the measure.
