Please explain to me how Fox News was an arm of the Bush administration. Because Karl Rove used to watch it and so did Dick Cheney?

Glenn Beck wasn't even on Fox for 95% of Bush's presidency, You had Alan Colmes on Hannity and Colmes, O'Reilly who criticized Bush on numerous occasions-- Palin wasn't on Fox back then either.
You simpletons fail to realize that there is a difference between being ideologically compatible with a cable news network, and openly attempting to use a cable news network as a scapegoat to excuse your pitiful results and poll numbers as POTUS. Fox is the only right of center news network in the entire MSM. The President was a republican. Why the fuck would the cabinet members of a republican president watch MSNBC, CNN, etc. to constantly be mocked and bashed 24/7?> Not once did Bush adress MSNBC by name or openly criticize the network as preventing the progress of America (whatever that means). Not once did Bush applaud Bill O'Reilly or Sean Hannity or any of the other Hosts on Fox.
If you can't see the difference between those two situations, then you probably aren't bright enough to understand most things that happen in politics or life.
