"I think the reason we lost is that the economy tanked under a Republican and people were very seriously looking for a change," Palin said today on "The Oprah Winfrey Show."
"I don't think I was to blame for losing the race more than I could have been credited for winning the race if I had done a better job."
Palin, whose book, "Going Rogue: An American Life," hits bookstores Tuesday, spoke candidly with Winfrey about the way she says she was told to act and speak during the campaign and the effect it had on her family.
Having been given flashcards to prepare her for the debates, the vice presidential candidate told Winfrey, one side of the card would have a question and the other side would have a series of "non-answers."

"If I were to respond to a reporter's question very candidly, very honestly … I'd be told afterwards that 'you screwed up,'" Palin said.
Palin said she liked having her clothes laid out for her during the campaign because it was "one less thing to worry about," adding, however, that there were times, particularly before her family appeared at the Republican National Convention, when she felt as though she were on the popular makeover show "What Not to Wear."
Also questioned about what she was told to eat during the campaign, Palin said she found it strange that campaign operatives talked to her about sticking to the Atkins diet at the same time the McCain-Palin numbers were tanking.
Referring to CBS' Katie Couric as "the perky one with the microphone," the former Alaska governor said she didn't' blame the U.S. public for thinking she was ill prepared for the vice presidential post after seeing her interview with Couric.
"It was supposed to be kind of a light-hearted, fun [interview]," Palin said. "If people only know me from that interview, I don't blame them for thinking I'm not qualified.
"I think that [Couric's] agenda was to not necessarily show me in the best light and not allow my mistake, my gaffe to go uncaught," said Palin, who flubbed Couric's question about which newspapers, books or magazines she read regularly.
Admitting that she had been annoyed with Couric's "badgering" and had even rolled her eyes at times, Palin, 45, said it was unprofessional of her to wear that "annoyance on her sleeve."
The first time Palin said she realized the McCain camp would control a lot of what she wanted to say was when news broke that daughter Bristol, then 17, was pregnant.
While Palin wanted to send a message that did not glamorize the issue of teen pregnancy, she said, she had little control over the final media statement, one Palin describes as suggesting that she and her husband, Todd Palin, were "giddy, happy" to become grandparents.
Palin described a call she received from Bristol, in tears and embarrassed that news of her pregnancy had become a "top news story."
