Hillary Clinton won't announce her decision on whether or not to run for president before the end of this year.

In an interview with ABC World News anchor Diane Sawyer, a preview of which aired June 8 on ABC's "This Week," the former secretary of state said that she won't announce any choice about a much-discussed potential 2016 bid before the midterm elections and the end of this year.

“You know, I’m going to decide when it feels right for me to decide,” Clinton said.

Sawyer asked Clinton if she thought the Democratic Party was “frozen” waiting for her to make her decision - a suggestion Clinton quickly rebuffed.

“People can choose whatever they choose to do on whatever timetable they decide,” she responded.

“I just don’t think that’s a real concern,” she added.

Clinton's status as the frontrunner to be the 2016 Democratic presidential nominee is underlined by a Washington Post-ABC News poll highlighted on the show. Most of the respondents - 59 percent - approved of Clinton's job as secretary of state, and 69 percent of Democrats and Democratic-leaning independents said they would vote for Clinton if the Democratic presidential primary were held today. That gives Clinton an enormous lead over Vice President Joe Biden, who came in second in that poll with 12 percent.

But it's not all rosy. Half of respondents disapproved of the way Clinton handled the 2012 attacks on the Benghazi consulate.
