It might be appalling that 10 percent of Americans believe Barack Obama is a Muslim, despite all of the reports to the contrary. Guess those bogus e-mails have an effect.
But when you consider what else Americans think, it starts to make sense. Ben Smith at Politico.com, compiled these beliefs based on public opinion surveys:
"22 percent believe President Bush knew about the 9/11 attacks in advance.
30 percent believe Saddam had weapons of mass destruction.
23 percent believe they've been in the presence of a ghost.
18 percent believe the sun revolves around the Earth."
Are you in any of those minority groups?
