I'm calling BS on this. I've never heard any credible person say bush has an inquisitive mind.
Recall that Condi was Governor Bush's foreign policy "tutor" in 1999.:
Note to Condi: Bush asking you where the hell Serbia is on a map, or asking you who the president of Russia is, does not qualify him as having a sharp, "inquistive" mind. Love may fool you into thinking it does. But, these are in fact, the questions of a moron or a dunce.
That's the sentence that stuck out for me too. Knowing what I know, I think it makes him sound down right infantile.
