We already know the numbers. Pew finds that 18% of Americans believe President Obama is a Muslim. A new Newsweek poll, taken after the controversy over the New York mosque, places that figure at 24%. Even if he's not a Muslim, Newsweek finds, 31 percent think it's "definitely or probably" true that Obama "sympathizes with the goals of Islamic fundamentalists who want to impose Islamic law around the world." When the focus is narrowed to Republicans, a Harris poll finds 57 percent of party members believe he is a Muslim, 22% believe he "wants the terrorists to win," and 24% believe he is the Antichrist. These figures sadden me with the depth of thoughtlessness and credulity they imply.
