At the end of their interview, Sean Hannity actually asks the tougher version of the resignation question.
Instead of asking why she resigned, he asks why she wouldn't resign as President.
HANNITY: Okay, so let's say it's 2012 and you decide to run, and the question comes up:
"Governor, what assurances [can you provide] that you won't resign if investigations begin, if you think you're a lame duck. How would you answer that question in 2012?"
PALIN: The decision to hand the reins over to my lieutenant governor was all about doing right for the constituents in the state of Alaska; not prohibiting progress based on the opposition researchers trying to put me on a path toward personal destruction.
So doing the right thing for my state. And the decision was the right thing for Alaska.
Okay -- Hannity. Perfect opportunity for a follow-up: Well, what if opposition researchers try to put you on a path toward personal destruction as President of the United States, so you can't move the country forward?
Do you think Hannity goes there?
This is why Palin's choice of interviews is so telling. No one on the list will ask the follow-up.
But of all the hundreds of questions she'll be asked on the tour, it's the one she most needs to answer.
