ABC News' Teddy Davis, Imtiyaz Delawala, and Rigel Anderson Report:
Sarah Palin discussed her upcoming "Saturday Night Live" appearance on Friday, telling Neal Boortz in a radio interview that she does not know what the late-night sketch comedy show has lined up for her while adding that it is a chance to "rise above the political shots that we take."
"I haven't seen a script -- not at all. They haven't even hinted about what that script is going to say," said Palin.
"But you know," she said, "I just want to be there to show Americans that we will rise above the political shots that we take because we're in this serious business for serious challenges that are facing the good American people right now. That's why we're campaigning hard. That's why we're working hard."
Asked if she is going to play Tina Fey, the actress who has been skewering the Alaska governor's debate performances and television interviews, Palin said, "I should. That's a good idea."
She then added: "Oh, I don't know what they have lined up."
Beyond previewing her SNL appearance, Palin was also asked about McCain's widely praised joint appearance with Barack Obama at Thursday's Al Smith dinner.
Boortz told Palin that people have been asking him, "Where has that McCain been?"
"(Laughter) I think that's the problem with campaigns," said Palin. "Doggone it. There aren't enough hours in the day to really be able to express all aspects of who a candidate is and where they want to lead this great country."
Palin was asked at the very end of her interview if she has ever heard of the "Fair Tax."
The Alaska governor indicated that she was familiar with it and expressed frustration with the current system but stopped short of endorsing the tax overhaul.
"I have" [heard of it] said Palin, "and you know what, in listening to it, and hearing more about it, we know that our current system is so doggone burdensome that anything would be better than our current tax code."
The "Fair Tax" proposal, which was championed by Mike Huckabee before he won this year's Iowa Caucuses, would replace all federal taxes with a 23 percent sales tax.
In order to offset its impact on the poor, the legislation would offer a monthly prebate to all Americans. The size of a household's prebate would be calculated by multiplying 23 percent -- the size of the new tax -- against the government-established poverty level for a household of that size.
According to the 2007 federal poverty level, an adult with no children would receive an annual prebate of $2,348 (which would come in monthly checks of $196). A married couple with two children would receive an annual prebate of $6,297 (which would come in monthly checks of $525).
Even though the "Fair Tax" is marketed as "revenue neutral," liberal tax policy experts have substantial questions as to whether a 23 percent retail sales tax on its own would adequately cover the current cost of government.
"If you haven't read the book, the head of your ticket has one," Boortz told Palin, referring to one of the books that he and John Linder have co-authored on the "Fair Tax."
