Three days after Sarah Palin was announced as the Republican vice-presidential candidate, the McCain campaign released a statement saying that her 17-year-old unwed daughter, Bristol, was pregnant. The baby's father, an 18-year-old former hometown hockey star, was thus thrust into the national spotlight. In the October issue of Vanity Fair, Levi Johnston explains what happened behind the curtains of the campaign—and inside the Palin home.

For "Me and Mrs. Palin," Johnston tells Vanity Fair his story about life with the Palin family—with whom he lived for two months after the election—over the course of his two-and-a-half-year relationship with Bristol. He turns a number of commonly held beliefs about the former governor—the purportedly loving mother, devoted wife, and prolific hunter—upside down.

The Palin house was much different from what many people expect of a normal family, even before she was nominated for vice president. There wasn't much parenting in that house. Sarah doesn't cook, Todd doesn't cook—the kids would do it all themselves: cook, clean, do the laundry, and get ready for school. Most of the time Bristol would help her youngest sister with her homework, and I'd barbecue chicken or steak on the grill.

Even before Palin became John McCain's running mate, she seemed worried about what a grandchild would do to her political career. According to Johnston, she had a plan for how to handle her daughter's unexpected pregnancy.

Sarah told me she had a great idea: we would keep it a secret—nobody would know that Bristol was pregnant. She told me that once Bristol had the baby she and Todd would adopt him. That way, she said, Bristol and I didn't have to worry about anything.

Sarah kept mentioning this plan. She was nagging—she wouldn't give up. She would say, "So, are you gonna let me adopt him?" We both kept telling her we were definitely not going to let her adopt the baby. I think Sarah wanted to make Bristol look good, and she didn't want people to know that her 17-year-old daughter was going to have a kid.

After the campaign, Johnston watched Palin turn into a different person. The result back home in Alaska was a woman ready to turn in elected office for money.

Sarah was sad for a while. She walked around the house pouting. I had assumed she was going to go back to her job as governor, but a week or two after she got back she started talking about how nice it would be to quit and write a book or do a show and make "triple the money." It was, to her, "not as hard." She would blatantly say, "I want to just take this money and quit being governor." She started to say it frequently, but she didn't know how to do it. When she came home from work, it seemed like she was more and more stressed out.
