Everywhere, the Muslim Brotherhood is benefiting from a democratization it did not trigger. There is a political vacuum because the liberal vanguard that initiated the Arab Spring did not try, and did not want, to take power. This was a revolution without revolutionaries. Yet the Muslim Brothers are the only organized political force. They are rooted in society, and decades of opposition against authoritarian regimes gave them experience, legitimacy and respect. Their conservative agenda fits a conservative society, which may welcome democracy but did not turn liberal.
