MSNBC leaning left for ratings?

From an article by NYTimes’ Jacques Steinberg, “Riding a ratings wave from ‘Countdown With Keith Olbermann,’ a program that takes strong issue with the Bush administration, MSNBC is increasingly seeking to showcase its nighttime lineup as a welcome haven for viewers of a similar mind. Lest there be any doubt that the cable channel believes there is ratings gold in shows that criticize the administration with the same vigor with which Fox News’s hosts often champion it, two NBC executives acknowledged yesterday that they were talking to Rosie O’Donnell about a prime-time show on MSNBC.”
UPDATE: Rosie writes on her blog she won’t be doing a show on MSNBC.
