MSNBC’s liberal purge continues with the news that Al Sharpton’s Politics Nation show is being sent to cable news Siberia by airing on Sunday mornings at 8 AM. Sharpton tried to spin his removal from weeknights as not a demotion. He told The New York Daily News, “I’m very happy. First, I can reach a wider audience of people who don’t get home by 6 at night. Second, I can now get the A-list guests and newsmakers I want. And third, a Sunday morning host is what I always wanted to be. I never wanted to be a weeknight pundit. I wanted to be a Sunday morning newsmaker. I wanted to be Dr. Martin Luther King, not Larry King.”
