Who needs Keith Olbermann when you have Al Sharpton? The reverend is in line to get his own show at MSNBC, according to the New York Post. He’ll replace Cenk Uygur at 6 p.m. Sharpton has been subbing for Uygur for three weeks already and has done well with older viewers. Sharpton also filled in in the 10 p.m. slot last month and posted better-than-average numbers. Sharpton’s spokeswoman denied any “formal discussions.”
