I won’t disagree that there are many libs at the CIA but that was a staged media op using very low level people who were supporters of his. Please don’t use that bit of video to base your assumptions on.
As far as staged, I saw Obama appear at other departmental headquarters and NONE of his appearances were greeted with such sustained and loud cheering, screaming and clapping in utter joy as at Langley.
Many articles and books were written calling the CIA a fifth column. I love your term "very low level" people. Others call them analysts. I, for one, don't believe the frenzied mass at that gathering is unrepresentative of the CIA. It needs to be cleaned up. Bush halfheartedly tried but failed.
