"I will look carefully at what I think I can do and make that decision sometime next year," she said.
Clinton said the country's economic concerns, including food stamps and a high unemployment rate, were more pressing than her future political prospects.
"It's such a difficult decision, and it's one that I'm not going to rush into," she said. "And I don't think we should be looking at the next election. I think we should be looking at the work we have today."
The former secretary of state said she did think it was important for the country to have a woman in the White House, although she didn't "know the exact timing of it or who that might be."
