CNN. The Clinton News Network. That bastion of journalistic integrity which, if you believe so-called 'moderates' represents one of the last two truly unbiased news sources in the United States. (The other, because they're not really moderate, is the laughably left-wing NPR.)
For liberals who are willing to drop the whole "oh, we don't own a TV shtick" and still subscribe to cable, CNN has become something of a public persona litmus test. By pledging their allegiance to the grand pappy of cable news nets, they can pretend they're not quite as crazy as MSNBC viewers, but are still better than those Right Wing Nut Jobs watching Fox.
