Actually, the Couric thing was NOT a mistake on Palin's part---she was blatantly lied to by that harpy Nicolle Wallace, who promised her that Couric would be an easy series of interviews.
Now, Wallace had previously worked for Couric and McCain had foisted her on Palin as the VP candidate's campaign chief of staff, and so at that time, Palin had every reason to believe that Wallace had fixed things up with Couric.
Of course, as it happened, Couric sandbagged Palin repeatedly, stalked her from event to event, and then hacked up the interview footage to make the Governor look like an idiot. From that point forward, Palin distrusted Wallace and the other professional GOP staffers who were assigned to her.
It's all recounted in Going Rogue.
Honestly, I didn’t think Sarah did all that wrong in that “interview” (inquisition) with Couric. “Katie” just got hold of a bone and fought over it until really, SHE was the one who looked silly. Sarah just simply didn’t have a long list of liberal rags (”newspapers”) to spiel off when “Katie” demanded it. I doubt most of us could spout off everything we read last week. The “Alaska Gazette” would just be fodder for Cupcake’s ridicule.
These “journalists” have, through their malfeasance and ignorance, foisted the biggest fraud and fakir on this country in our lifetimes.
