Winfrey began the interview by asking Palin if she felt snubbed atnot getting an invitation to appear on the show last year.Winfrey said she didn't have any candidates on her Chicago-based showduring the campaign because of her support for President Barack Obama.

Palin said she didn't feel snubbed and told Winfrey, "No offense to you, but it wasn't the center of my universe."

Palin said in another interview broadcast Tuesday that a 2012presidential bid is "not on my radar," but wouldn't rule out playingsome role in the next presidential election.

"My ambition, if you will, my desire is to help our country in whateverrole that may be, and I cannot predict what that will be, what doorswill be open in the year 2012," she told Barbara Walters.

When asked whether she'd play a major role, the former Republican vicepresidential candidate replied that "if people will have me, I will."
