Frank Luntz Returns?

I can't imagine any other explanation for the following shift in Palin's word choice documented on Hotline [emphasis mine]:

QUESTION: (NBC) Why did your husband decide to change his mind and return to Alaska and testify?

A: He's always been an open book about this whole Tasergate issue, wanting to speak with investigators, wanting to speak and is with attorneys, everybody involved. The personnel board in the state of Alaska is that board tasked with dealing with any issue involving the governor, the lieutenant governor, or the attorney general.

Of course, the obvious question is: if the firing was not about a family squabble, then what sense does it make to reference a taser?  

She winds up the discussion with:

It's an open book. Nobody has anything to hide. Nobody's done anything wrong. My choice, and my responsibility to replace a cabinet member, an at-will exempt political appointment whom I did replace, because his strengths were in other areas. It wasn't in running an entire department. There was some, some duties there that he was not able to fulfill.

Yeah, the "duty" of firing your ex-brother-in-law.
