I need to go back and study it some more, because from the abstract at the bottom, titled "Knowledge Levels by News Source", The Daily Show/Colbert Report looks like it's tied or bested in almost every category by folks who read newspaper websites. In fact, if you call the margin of error around 4%, there's really not much difference in the top several items. And I can't believe something like this would be accurate down to 1 or 2 percentage points or less.
