"She wants to be president of the United States, and she has not been coy about that," says CBS News' Scott Conroy, who followed Palin on the 2008 campaign trail.
Conroy and Shushannah Walshe, who covered Palin for Fox News, both guests today on Washington Unplugged, will be releasing a book in January about Palin.
In some respects, Palin's resignation was not very surprising, Conroy and Walshe say, given her experiences back in Alaska after campaigning as the Republican vice presidential nominee in 2008.
"It was very, very clear her return to her home state was exremely difficult for the governor," Conroy says.
Many of her allies in Alaska's legislature turned against her after she developed a national presence, and one of her harshest critics in Alaska even referred to her as a "political sociopath," Conroy says.
"Even though she does remain popular in her home state, it's nothing like in the lower 48 where she's mobbed by fans," Walshe says. "She wants to come back to those crowds."
