Network sources tell Playbook that Keith Olbermann was suspended because he refused to deliver an on-camera mea culpa, which would have allowed him to continue anchoring "Countdown." Olbermann told his bosses he didn't know he was barred from making campaign contributions, although he is resisting saying that publicly. Olbermann may not hold as many cards as he thinks. He makes $7 million a year and MSNBC's prime time is not as dependent on him as it was before the addition of Rachel Maddow and Lawrence O'Donnell, who make considerably less.
