Marc Lynch writes for Foreign Policy magazine:
Tunisia's post-revolutionary politics are being profoundly shaped by the meteoric rise of the long-banned Islamist movement al-Nahda. Decades of fierce repression during the regime of former President Zine el-Abedine Ben Ali crushed almost every visible manifestation of Tunisia's Islamist movement. The banned movement played a very limited role in the revolution. But since Ben Ali's flight and the triumphant January 30 return of exiled leader Rached Ghannouchi, al-Nahda has grown with astonishing speed. A recent survey found support for the party at just below 30 percent, almost three times that of its closest rival. Its ascent is fueling a dangerous polarization, leading putative champions of democracy to endorse the postponing of elections, and frightening many secularists and women who fear for their place in the new Tunisia.
I have just returned from a trip to Tunisia focused on the resurgence of al-Nahda. I emerged impressed with al-Nahda's organizational strength, democratic rhetoric, political energy, and by their determined efforts to engage with their political rivals and reassure their critics. But I also emerged with real concerns about the growing polarization and collapse of trust across the political class, which risks dividing the Tunisian public and crippling the desperately needed democratic transition. And I found even al-Nahda's leaders unsure about how to grapple with the rising salafi trend, which may be more of a source of weakness than a source of electoral strength.
