There is a somewhat surreal correction in the current Economist with respect to evolution and America:
Feb 12th 2009
From The Economist print edition
In "Unfinished business", published on February 7th, we said in the United States a Gallup poll found that only 15% of people agreed with the proposition that "humans developed over millions of years", up from 8% in 1982. The figures should have been 14% and 9% respectively. This was corrected online.
In other words, the situation is even worse than you think, albeit not statistically significantly so.
