Here is the answer to your "Why?" question:
That study, included MSNBC also, but it did NOT include those who did NOT watch the news.
IOW, they did not poll those non-newswatchers. They only polled THE newswatchers.
It was the University's opinion that non-newswatchers would be more accurate in answers.
