According to The Pew Research Center, 18% of Americans say that Pres. Barack Obama is a Muslim.
In other wingnut news, an April New York Times/CBS News poll found that 20% of those surveyed believe that Pres. Obama was born outside the U.S.
Apparently I'm not the only one who wonders about these 20%ers. Yesterday's edition of The Washington Post included a brief article noting (among other things) that one in five Americans admits to peeing in a swimming pool.
I suspect that these are the same numbskulls (18%) who are more likely to vote for a candidate if Sarah "Mama Grizzly" Palin campaigns on their behalf.
