Sarah Palin tries to set the record straight in her new memoir, "Going Rogue: An American Life." In it, she reveals behind-the-scenes details of the 2008 campaign as the Republican vice presidential nominee, and how the run affected her family.
Speculation has swirled that Palin, instead of pursuing a 2012 political run, may join the media, and, following in the footsteps of other GOP pundits, host her own talk show. But Palin told Barbara Walters that a talk show is not in the "best interests" of her family.
"Well, I'd probably rather write than talk. But I don't know if that would...be something that is in the best interests of my family right now," she said. "There have been lots and lots of offers, in these last couple of months especially, coming our way, some bizarre things," Palin said.
"I would not ever want to put my kids through such a thing," she said, "Our life has become kind of a reality show."

It was Bristol who, at age 17, surprised the nation when her pregnancy was announced in September 2008. Bristol gave birth to son Tripp in December.
Palin said that she did not know her daughter Bristol was sexually active before learning of her pregnancy.
"That is why it was shocking. And that's the understatement of the century, too, that we were shocked," Palin said "Truthfully, we were devastated."
To a certain extent, she said she felt as if she had fallen short as a mother.
"Perhaps there was that feeling of, 'Bristol didn't, why? Didn't you know there are things you could do to prevent this, or not do it at all?'" she said. "So, yeah, a parent's responsibility, perhaps feeling that I, I let her down. I think that's just a mother's nature."
Before learning of Bristol's pregnancy, Palin said she had talked with her daughter about the virtues of abstinence and using birth control "with just that assumption that, well, good, I'm glad you're not doing it."
When asked by Walters if she would have allowed Bristol to have an abortion, Palin said she "would have counseled her to choose life."
News of Bristol's pregnancy was an unwelcome controversy -- just days after the Republican presidential nominee John McCain chose Palin as his running mate. Addressing rumors, Palin said she never tried to keep her daughter's pregnancy a secret.
"Wasn't trying to keep it secret, and, and wouldn't have been able to, anyway. But the vetting team knew that Bristol was pregnant," she said. "It was released to the media before I could talk about it, and before Bristol could talk about it. And that was unfortunate, because teenage pregnancy is a problem in America, and we did not want it to be glamorized."
Palin also said that the pregnancy was the first in a series of miscommunications between the McCain campaign and Palin, which resulted in public perception that Palin, 45, and her husband Todd were overjoyed about the birth, when in fact she advocates teen abstinence.
