By one count, about a fifth of Americans incorrectly believe Barack Obama is a Muslim. (He is a Christian.) That's messed up. Know what's more messed up? That half of Republican voters in Alabama and Mississippi think he is. Of course, there's nothing wrong with being a Muslim. And it would be fine with me if our president were a Muslim. But he isn't. Now, maybe some of the Deep Southern GOPers who told Public Policy Polling they think Obama follows Islam don't actually think so, but rather were using "Muslim" as a proxy for "not a real American," or "someone I don't relate to," or, who knows, "a guy with terrorist sympathies." Also messed up. This and other news, good and bad, in today's Threat Assessment photo gallery.
