For those interested in seeing Sarah Palin interviewed by someone who is asking her questions rather than trying to trap her (not that there's anything wrong with that), we have her in Charlie Rose's Green Room.
I have gone back and looked at the Couric video. I see what the fuss was about, because she was clearly flustered and lost - not very inspiring. On the other hand, what is happening in the interview is that she is being asked to support her claim of a particular good thing that McCain is known for. She can't come up with one, and she does not BS her way out of it as a good politician should. When you look at it, she is being asked about the specifics of McCain's legislative record. I'm not sure that should be the first priority of a governor-turned-VP nominee in getting up to speed.
For comparison #1, look at the questions Couric asked Obama. All are easier to answer. There's nothing of the nature of "What were the anti-corruption measures sponsored by Joe Biden that caused you to choose him for your VP?"
For comparison #2, Hillary Clinton did not finally face the media on a consistent, non-managed basis until this last year, 16 years after she has come into the national spotlight. When she had been interviewed in the past by tenacious people - the Tim Russert interview, her Vast Right Wing Conspiracy, and all her "I'm sorry I don't recall" deposition - she was repeatedly a disaster. She's not anymore, but she was sheltered from hard questioning for decades.
I have got to stop writing about politics. I'm making myself crazy.
