A new Pew survey found that only 69% know that Dick Cheney is vice president, whereas back in 1989, 74% could identify ol' Dan what's his toes. According to this summary in Editor&Publisher
Pew judged the levels of knowledgeability (correct answers) among those surveyed and found that those who scored the highest were regular watchers of Comedy Central's The Daily Show and Colbert Report. They tied with regular readers of major newspapers in the top spot -- with 54% of them getting 2 out of 3 questions correct. Watchers of the Lehrer News Hour on PBS followed just behind.
Virtually bringing up the rear were regular watchers of Fox News. Only 1 in 3 could answer 2 out of 3 questions correctly.
