Don't sell Sarah Palin short. As the parties approach the time to select the next nominee, she will have had several years of coaching, reading, study, and time to reflect on what went wrong last time.
I have a vision of the NEXT Palin/Couric interview. I suspect Palin will be much better prepared, and have memorized all the buzz phrases which will wipe the floor wiith Couric and endear her to the wider Republican base.
