WATCH Hillary Rodham Clinton Expected to Announce She's Running for President

Hillary Clinton is moving toward announcing her candidacy for president of the United States likely on Sunday, according to Democrats familiar with her plans.

Her announcement will come via social media, including a video message, they say. In fact, Clinton has already filmed the video she’ll use to announce her candidacy. Early state visits could come as soon as next week with Iowa the most likely first stop.

Clinton’s all-but-certain 2016 presidential bid marks the second time she has tried to become the first female to win the White House.

After her defeat at the hands of Barack Obama in 2008, Clinton firmly said “no” when asked whether she would ever run for president again. But, since then, her position has evolved.

In recent months, Clinton has been gearing up for her campaign. Behind the scenes, she has hired a robust team, including many of President Obama’s former advisers and strategists.

Her team also recently signed a lease for a new office space in Brooklyn, New York, which will serve has her campaign headquarters.

She will enter the race as the clear front-runner for the Democratic presidential nomination, and is leading all her possible Republican opponents in early polls.

A recent ABC News-Washington Post poll showed Clinton ahead of potential Republican candidate, Jeb Bush, by a 54-to-40 percent margin in a prospective match-up, with even bigger leads against Sen. Ted Cruz, Gov. Scott Walker and Sen. Marco Rubio.
