Hillary Clinton Decision On Presidential Run Not Likely Until 2015

Former Secretary of State Hillary Clinton says it may be next year before she decides whether she'll run for president.

The former first lady embarks on a book-signing tour this week for "Hard Choices," which is to be released Tuesday.

"I will be on the way to making a decision by the end of the year, yes," she said in an interview played in part Sunday on ABC's "This Week." The full interview will air Monday night.

"Certainly not before then," she added. "I just want to kind of get through this year, travel around the country, sign books, help in the midterm elections in the fall and then take a deep breath and kind of go through my pluses and minuses about what I will -- and will not -- be thinking about as I make the decision."

Clinton is the favorite among possible Democratic presidential nominees. An ABC News-Washington Post poll released Sunday gives Clinton 69 percent support among Democrats and Democratic-leaning independents.
