Long-time progressive champion Rep. Barbara Lee (D-Calif.) on Monday officially announced her widely speculated and highly anticipated candidacy to serve as chair of the Democratic Caucus, the party’s fourth-highest ranking position in the House, for the next congressional session.

“Whether it’s working across the aisle to enact HIV/AIDS laws, or bringing the Sanders and Clinton campaigns together behind a cohesive and progressive Democratic Platform, my career has been dedicated to finding common ground and delivering results,” Lee wrote in a letter to her Democratic colleagues.

The letter outlines “three deeply held beliefs” on which Lee is basing her campaign:

1. The strength of our caucus lies in our diversity of experiences and ideas.
2. Our caucus is at its best when everyone has an opportunity to contribute and collaborate.
3. Our caucus has the talent and the vision to improve the lives of all people.

“There is nothing more important than returning bold Democratic leadership to Congress,” Lee’s letter declares. “By putting people first, we will regain the majority and strengthen it for the future.”

“I know many Trump districts and rural districts and I know how people are struggling and suffering. …It’s about communicating that, and that’s what I want to do—bring people together.”
—Rep. Barbara Lee

Lee is facing off against a fellow congresswoman from California, Linda Sánchez, who beat out Lee’s 2016 bid to serve as the caucus’s vice chair by just two votes.

The chair role is currently held by outgoing Rep. Joe Crowley (D-N.Y.), who was often seen as the heir to House Minority Leader Nancy Pelosi until last month, when he was defeated by primary challenger Alexandria Ocasio-Cortez, a political newcomer and vocal democratic socialist who trounced Crowley by a full 15 points.

Ocasio-Cortez, who is 28, is among the Democratic candidates and members of Congress who have spoken out in favor of 72-year-old Lee’s candidacy. While Lee is aware of the growing demand for the Democratic Party to elevate a new, younger, generation of leaders, as she told Politico, “millennials and young people know my record—it’s really about our ideas, how we engage with people, and how we listen to what the new generation is saying to us.”

If selected, Lee would be the first African-American woman, Democrat or Republican, to hold a congressional leadership position. “When you look at the history of the Democratic Party and the Democratic leadership, African-American women,” she said, “we’ve been the backbone of the Democratic Party—we should be in the face of leadership also.”

Although she is aware of the potential milestone, Lee emphasized her ability to unite Democrats across demographics. “Poverty affects everyone: rural, urban, people of color, and white working class,” she said. “We have a lot more in common than not…and the Republicans and [President] Donald Trump have tried to divide us.”

“If Barbara Lee becomes Democratic Caucus Chair, it would represent a major ideological shift in the party leadership. Lee has co-sponsored Medicare for All, free college, reproductive rights, private prison ban, and keeping fossil fuels in the ground.”
