Fox keeps politics in one place: FNC.
Just turn on the radio. No liberals allowed.
True and in recent years Fox has gotten some of their O&O's like KTVU San Francisco to expand their 10pm newscasts to run at 11pm to compete against other O&O's in the DMA8 market.
I don't see Fox considering putting their national Late Night show for now though given the recent shifts to having an 11pm newscast in some cities for their O&O's though.
