Intercollegiate Studies Institute organized an exam of civic knowledge among citizens and elected officials in the US.  Although the average citizen failed with only 49% correct answers, elected officials were even worse with 44% correct!  http://uk.news.yahoo.com/18/20081120/tod-us-officials-flunk-test-of-amerian-h-f62056d.html  Pretty sad when the people running the country don't even understand it.

Here is the actual test that the majority failed:http://www.americancivicliteracy.org/resources/quiz.aspx

I took the test and got 28 out of 33 correct.
