Sure, 10 percent of Americans may think that Barack Obama is a Muslim, but as Ben Smith notes, 22 percent believe Bush knew about 9/11 in advance, 30 percent believe Saddam had weapons of mass destruction, 23 percent believe they've been in the presence of a ghost, and 18 percent believe the sun revolves around the earth. In other words, it's always going to be the case that a certain minority of the country believes wildly untrue, and potentially even vicious, things. The question, politically speaking, is how big a minority, where do they live, and do they vote? Frankly, my hunch is that Barack Obama's candidacy is more in danger from voters who believe him a black man than voters who believe him a Muslim.
