America has gone to the Nutters.

Astonishingly, a Newsweek poll finds that 52 percent of Republicans believe that it is “definitely true” or “probably true” that “Barack Obama sympathizes with the goals of Islamic fundamentalists who want to impose Islamic law around the world.” So a majority of Republicans think that our president wants to impose Islamic law worldwide.

That kind of extremism undermines our democracy, risks violence and empowers jihadis.
