On that specific response, I agree. However, I think the truth is that the accusation had just come out, and she probably didn’t know enough at that time to give a better answer. IIRC, the accusation was first made hours before the interview. I suspect McCain’s staff was still digging in to the details, and it would have been far worse if she had offered INCORRECT details as part of her answer.

CBS New anchor Katie Couric ordered staff to drop all references to “Governor” or “Gov.” from her interview with Alaska Gov. Sarah Palin. When a staff member pointed out that in other venues, Couric and CBS News had referred to Governor Palin’s opponent, Joe Biden, using his title of “Senator” or the abbreviation, Couric, according to a CBS News editorial aide, sought approval from CBS News management to drop the “Governor” reference during her broadcast interview with Palin that began on Wednesday night.
