Is the Rev. Al Sharpton about to land his own show on MSNBC? The network isn’t commenting about the possibility, raised today by TVNewser. But the web site says it’s being considered after the controversial civil rights activist generated decent ratings over the last two weeks while hosting the 6:00 PM ET  newscast MSNBC Live. He filled in for radio talk show personality Cenk Uygur, who has been on vacation. The site says that Uygur “will remain a part of MSNBC in some capacity.”
