"Let me say this, hypothetically speaking, I really do hope that we have a woman president in my lifetime," Clinton told a private audience in Toronto. "And whether it's next time or the next time after that, it really depends on women stepping up and subjecting themselves to the political process, which is very difficult."
Clinton, a Democrat who was secretary of state under President Barack Obama, a former senator from New York and is the wife of former President Bill Clinton, is said to be undecided whether to seek the presidency in 2016.
Many Democrats and Republicans in the United States are expecting her to run, although the 65-year-old Clinton has said she needed to rest after four years as a globe-trotting secretary of state.
Polls have indicated she is far and away the most popular potential Democratic candidate for 2016, and that most Americans would prefer her to several possible Republican contenders.
