"She does indeed even look down briefly."  or would it be more actuate to say: She does indeed even look down repeatedly? She does indeed even look downward a lot? She does fail to maintain eye contact when trying to answer questions?

Of course the video containing the 2008 Obama/Hillary debate is nearly two hours long. I notice every time Hillary shows signs of being cornered by a certain question her eye's are everywhere but looking back at the moderator or into the camera. 

Maybe you weren't aware there is a great deal of psychology devoted to the study and question of difference between objective and subjective evaluation. My wild guess would be perhaps you fit the 'subjective' narrative more closely that is effected by personal feelings and prejudice.
