If the CIA was politicized enough  to support George W's invasion of Iraq (the liberal cant for the last 16 years ) why should we assume it isn't doing the same after eight years of providing the intelligence preferred by the Obama regime?  

The CIA is a lot of things; apolitical is not one of them.  

Even their 'country studies' which you cite have a definite slant to them.   Particularly when they 'describe' the various political systems.   The 'slant' changes about as often as the Secy of State's bureaucrats change their socks.  That's why the SoS has 'talking points'; to get out the current position of the current administration. The CIA, the NSA, the DIA and all the other intel agencies massage their 'product' to meet political needs.
