Secretary of State Hillary Clinton has again said she is not planning another presidential bid.

"I've said I really don't believe that that's something I will do again,"  Clinton said in the interview, which airs Wednesday night as part of Barbara Walters "10 Most Fascinating People" special. (In the above clip, Walters asks the other question apparently on every voter's mind -- what does Clinton do with her hair?). "I am so grateful I had the experience of doing it before."
