Hillary Clinton has secured the endorsements of 93 members of Congress ahead of her planned run for the presidency in 2016, according to a survey conducted by the Hill. Her backers include more than half of the Senate’s Democrats.

Clinton’s endorsers include 65 of the 188 Democrats in the House of Representatives as well 28 of the 45 Democrats in the Senate, the survey found. She also has the backing of 21 of the House’s female Democrats.

She received 99 Democratic endorsements in her 2008 bid for the Democratic Party’s nomination, which she ultimately lost to current President Barack Obama. If elected in 2016, Clinton would become the first female president in the country’s history.

The 67-year-old former first lady and secretary of state officially announced her candidacy in a video published to her website Sunday. Separately, Clinton campaign Chairman John D. Podesta emailed top donors and said she would hold a formal event to begin her candidacy in May.

“Every day Americans need a champion. And I want to be that champion,” Clinton said in her announcement video. “So I’m hitting the road to earn your vote, because it’s your time. And I hope you’ll join me on this journey.”

Clinton traveled to Iowa this week to meet with potential voters and discuss the platform on which she will run. She identified four major tenets for her campaign, including a focus on strengthening America’s economy for the future, addressing the needs of the nation’s families, national security interests and the removal of dysfunctional aspects of government, according to the Associated Press.

“I think it’s fair to say that as you look across the country, the deck is still stacked in favor of those already at the top,” Clinton told onlookers at a community college in Iowa. “There’s something wrong with that.”
