Dems complain about a conservative bias at FOX News, FOX News says fuck you. Republicans complain about liberal bias at MSNBC, and heads roll.

MSNBC tried a bold experiment this year by putting two politically incendiary hosts, Keith Olbermann and Chris Matthews, in the anchor chair to lead the cable news channel’s coverage of the election.

That experiment appears to be over.

After months of accusations of political bias and simmering animosity between MSNBC and its parent network NBC, the channel decided over the weekend that the NBC News correspondent and MSNBC host David Gregory would anchor news coverage of the coming debates and election night. Mr. Olbermann and Mr. Matthews will remain as analysts during the coverage.

The change—which comes in the home stretch of the long election cycle—is a direct result of tensions associated with the channel’s perceived shift to the political left.

Politically incendiary hosts are only permissible when they’re right-wingers. Please make a note of it.
