He's a former Democratic senator from North Carolina and a former vice presidential candidate. Gayle welcomes John Edwards to talk about his political aspirations, his family and his new book.

In Home: The Blueprints of Our Lives, John captures the stories of 60 people who share their memories of their childhood homes. John says he was careful to make the distinction that "home" doesn't mean the physical structure, but rather "the place that you grew up and the people that you grew up around."

Having spent much of his childhood around his grandparents and extended family in the South, John says he wanted to showcase the others' stories of "home." "What I wanted was as much diversity as possible—geographic, income, background, racial, male and female, everything," John says. "But what I didn't know is when all the stories started coming in, how similar they'd be. Whether you grew up on an Indian reservation…or in New York City in the Bronx, it doesn't matter—people remember the same kinds of things. It's overwhelming how connected we all are at a very basic level."

John also talks to Gayle about the hardships he's faced in his life, including the death of his 16-year-old son, Wade, who was killed in a car accident in 1996. How did he deal with the grief? "Honestly, it was just putting one foot in front in the other," he says. "I wish I could say it was something complicated." In addition, John talks about his wife's battle with—and recovery from—breast cancer. "Her health is good, she's cancer-free and I'm knocking on wood, but she is great," he says.

As for his political plans, John hints to Gayle he may be running for president in 2008. "In the next few months I'll make a decision about it," John says. "There is certainly some movement in that direction; I'll leave it at that!"
