I don’t watch her 8 p.m. show on Headline News, but, quietly, she’s challenging Olbermann for No. 2. For example, Thursday’s rating in the 25-54 demographic had O’Reilly 774, Olbermann 508, Grace 473, and Brown 389. And she beat him on Wednesday 595-547.

TV Newser has historical numbers here and we’ll see if Grace’s strength plays out long term, but maybe MSNBC is in trouble without George Bush to kick around?
