Square One endorses Lauren Babb Tomlinson (CA-06)
Today, Square One announced its endorsement of Lauren Babb Tomlinson for Congress in California’s 6th Congressional District, backing a proven advocate, former union organizer, and working mother in one of the most competitive House races in the country.
Lauren Babb Tomlinson is the only Black woman running in a red to blue U.S. House seat nationwide this cycle — at a moment when representation and effective leadership in Congress have never mattered more.
“Lauren Babb Tomlinson represents exactly the kind of leader Square One was built to support,” said Tony Vargas, Square One’s Executive Director. “She has the heart, the grit, and the sense of purpose to not only win this race, but to lead and deliver once she’s in Congress. Lauren understands what working families are facing because she’s living it herself, and she has spent her career fighting to make their lives better.”
A former union organizer and public affairs leader for Planned Parenthood Mar Monte, Lauren has spent her career expanding access to healthcare, standing up for workers, and advocating for families across the region.
Raised by strong women who instilled in her a deep commitment to service, Lauren’s path to leadership was shaped early by helping care for her grandmother who battled Alzheimer’s disease. Today, as a working mother, she sees firsthand the pressures families face — from rising housing costs to the growing gap between wages and the cost of living.
"I'm honored to receive the endorsement of Square One, an organization doing the hard work of building real political power for communities that have been overlooked for far too long. I'm excited to have them in my corner as we fight to flip CA-06 and deliver the change families in our district deserve."
California’s 6th Congressional District is expected to be one of the key battlegrounds in the fight for control of the U.S. House in 2026. The district represents a critical opportunity to elect a new generation of leadership focused on lowering costs, strengthening healthcare, improving public safety, and building an economy that works for everyone.
Square One supports and invests in high-potential Democratic women, people of color, and LGBTQ+ candidates running in competitive districts across the country.
Lauren Babb Tomlinson is joining the current slate of Square One’s endorsed challenger candidates for the 2026 cycle including: Carol Obando-Derstine (PA-07), Christina Hines (MI-10), Denise Powell (NE-02), JoAnna Mendoza (AZ-01), Randy Villegas (CA-22), Rebecca Bennett (NJ-07), Marni von Wilpert (CA-48), Pia Dandiya (FL-21), and Bridget Brink (MI-07).
