Hillary Clinton officially announced Sunday she will seek the Democratic nomination for president of the United States in 2016, ending years of speculation on if she would seek the White House for a second time.

The announcement came Sunday afternoon with the launch of a new HillaryClinton.com campaign site, which featured a video titled “Getting Started.” The video opens with stories of Americans planning for the future and features Clinton’s announcement.

“I’m getting ready to do something, too. I’m running for president,” Clinton says in the video. “Americans have fought their way back from tough economic times, but the deck is still stacked in favor of those at the top.”

An email was sent to her 2008 campaign alumni and past donors shortly before the website launch saying she will travel to Iowa and hold a formal campaign kick-off next month.

“Everyday Americans need a champion, and I want to be that champion,” Clinton says in the video. “So you can do more than just get by. You can get ahead, and stay ahead, because when families are strong, America is strong. So I’m hitting the road to earn your vote because it’s your time. I hope you’ll join me on this journey.”

Clinton, 67, has served in several political capacities during the past 30-plus years. She was First Lady of Arkansas from 1983-1992, First Lady of the United States from 1993-2001, New York’s junior senator from 2001-2009 and most recently, secretary of state under President Obama from 2009-2013.

In 2008, Clinton was seen as the frontrunner for the Democratic nomination for president, but wound up coming in third place in the Iowa caucuses. She would go on to win only 21 states and later suspended her campaign in June to endorse then-Sen. Barack Obama.

“I think candidates always learn from their previous campaigns,” said Dianne Bystrom, director of the Carrie Chapman Catt Center for Women and Politics at Iowa State. “I think she’ll learn a lot from that campaign. I think the political landscape is a lot different [now in 2015] than it was in 2007. In that campaign, she came out big and strong, had a huge organization and hit pretty heavy, but I think she learned from the fact that she cannot take anyone for granted.”

Clinton is set to travel to Iowa in the coming days and will opt for smaller meetings instead of large rallies.

On Tuesday, April 14, Clinton will attend a roundtable with students at Kirkwood Community College’s Jones County Regional Center at 1:15 p.m. On Wednesday, Clinton will tour Capital City Fruit, a family-owned business in Norwalk, at 11:45 a.m.

“I actually met her and all the other Democrat and Republican candidates in 2007, and found her to be very personable,” Bystrom said. “I felt like she was very good one-on-one with people, she has the capability of doing that.”

Clinton is the first Democrat to jump in the 2016 race. It is unknown if Clinton will have a serious primary challenge, but so far, former Maryland Gov. Martin O’Malley, former U.S. Sen. Jim Webb of Virginia and U.S. Sen. Bernie Sanders of Vermont seem positioned to challenge Clinton.

Progressive Democrats have called on U.S. Sen. Elizabeth Warren, D-Mass., to jump into the race, but she has repeatedly said she is not running.

“I think she’ll bring a message of “fairness” to the middle class,” Bystrom said. “What you’ve seen recently is her talking a lot about the middle class and the economy.”

Bystrom also said that type of economic message might win over some Elizabeth Warren supporters who are looking for a more progressive Democratic candidate this election.

Clinton will also inevitably face questions over two controversies that have made headlines recently, including her use of a private email server as Secretary of State and the Clinton Foundation accepting donations from foreign governments.

Clinton will not roll out detailed policy positions immediately, but the AP reported Saturday that Clinton’s campaign would focus on “boosting economic security” and “expanding opportunity of working families.”
