MSNBC vs Fox

One difference, clearer after the Olbermann suspension:

News Corp made multiple undisclosed donations to the Republican Governors Association, totaling at least $1.25 million, in addition to a $1 million contribution to the U.S. Chamber of Commerce for its pro-Republican election-year activities. Fox News has helped GOP candidates raise money on the air; Fox News personalities are featured guests at Republican fundraisers; while other Fox News personalities continue to help generate financial support for Republican candidates now, even after the elections.
