"That's why I was so shocked," Palin tells Barbara Walters in a new interview. "Truthfully, we were devastated."
In her sit-down with Walters, set to air Tuesday on Good Morning America, Palin talks about her public life and political aspirations during the 2008 presidential election. The former vice presidential nominee's highly anticipated book, Going Rogue: An American Life will be released the same day.
Palin's 15-year-old daughter Willow also spoke, revealing she has her own hopes for her mother in the political sphere. Willow told Walters that it "would be cool" to see her mother become president.
The interview will also air on ABC's World News, Nightline and on 20/20 on Friday.
