US Secretary of State Hillary Clinton has said she would not serve
a full eight years if President Barack Obama wins another term, hoping
eventually to retire to writing and teaching.
Clinton, who has
spent two decades in the national spotlight and narrowly lost her own
bid to be president in 2008, said she enjoyed her job as the top US
diplomat but found it physically grueling.
Asked by talk-show host Tavis Smiley if she would serve eight years, she replied: "No, I really can't."
