Interesting page number for that information.
Isn’t Norquist married to a Muslim?
yes. Sammah Alrayyes.
From the article: "In 2004, at age 48, Grover married a Palestinian Muslim named Samah Alrayyes, a Kuwaiti Public Relations specialist who was formerly a director of the Islamic Free Market Institute and specialist at the Bureau of Legislative and Public Affairs at United States Agency for International Development (USAID). (USAID is the United States federal government agency primarily responsible for administering civilian foreign aid.) The couple have two children adopted from abroad. (The Islamic Free Market Institute was founded by Norquist and Khaled Saffuri.) Grover has said he's a "white bread Methodist," however, a devout Muslim like Samah supposedly would not marry a non-Muslim, and of late, Grover has refrained from answering the question of his religion."
