Goes to show how effectively the "liberal media" myth has been spread.
How so?
People believe that all media is automatically biased, even if they know absolutely nothing about it (as the 74 percent who don't trust CSPAN to be fair clearly don't).
There is a difference between
not trusting a source, and
distrusting it. Accepting King's interpretation of the results (I have not seen the wording of the question), they tell us nothing whatsoever about
distrust.
EDIT: BTW... since when has C-SPAN provided
any form of reporting?
