No, I believe this is supposed to be an expression of Bolten's belief. But Scarborough is saying that Bolten would have never let the leak of his views get out unless W had approved it.
I do not want to open up the festering wound of the Harriet Miers nomination, but I do believe that it was the beginning of Bush's downward spiral that nothing seems to cure. His arrogance in telling us we had to "trust him" over something so obviously flawed caused an awful lot of people I respect to [figuratively] wash their hands of Bush and declare his presidency "finished".
