From David Folkenflik, NPR Morning Edition:
It's pretty easy to see the winning formula for Fox News and MSNBC. They spend their evening hours stoking outrage from the political right and left, respectively.
But it's not as clear what the missing secret sauce should be for CNN. The cable news pioneer now continually lags in ratings during prime time, the most heavily watched hours.
Mark Whitaker, acknowledges CNN has been thrown off course.
