This is the first I've heard of this side of her. The other day someone on FR described her showing her bias during softball questioning of some politican or during the discussion. Sorry, but I can't recall details. I'm willing to change my opinion of her if more information like the Boxer interview becomes available.
I agree with your assessment of some bias and softball questions to Dims by Kirran. I'm reserving judgment as well (maybe it depends upon who the producer of the show is and/or who is typing the questions in the teleprompter??)
