Dione Sims traveled to the Texas Capitol hoping to make her voice heard. She returned home wondering whether she was being called to do something much bigger.
On August 1, 2025, Sims sat inside the Capitol awaiting an opportunity to testify against a controversial congressional redistricting proposal. She never got the chance to speak. But something she heard that morning stayed with her: the proposed maps might favor one political party, but winning elections would still require candidates willing to run.
The following morning, she began considering who might challenge the newly drawn congressional district. Every person she considered seemed to have a reason not to run.Then came three unexpected words. “Why not you?” For Sims, the granddaughter of Ms. Opal Lee, affectionately known as the “Grandmother of Juneteenth,” the question carried an extraordinary responsibility. “If Juneteenth meant anything,” Sims told me during our interview, “it meant fighting for the freedom of the people.”
Today, Sims is the Democratic nominee for Texas’s 25th Congressional District, challenging a longtime Republican incumbent. But her candidacy represents something larger than another congressional contest. It raises a compelling question about the relationship between historical progress and the responsibility of each generation to advance it.
From Celebrating Freedom to Defending It
For decades, Sims has helped transform the meaning of freedom into tangible opportunities for others. Alongside her grandmother, who recently celebrated her 100th birthday, Sims helped advance the movement that culminated in Juneteenth becoming a federal holiday in 2021. She also served as founding executive director of the National Juneteenth Museum. Yet her contributions extend beyond preserving history.
In 2000, Sims founded Unity Unlimited, a Fort Worth nonprofit dedicated to education, cultural understanding, and community development. Through initiatives supporting entrepreneurship, food security, and workforce opportunities, she has worked to make freedom meaningful in everyday life. Her congressional campaign reflects that philosophy.
She believes freedom should mean affordable healthcare, economic stability, educational opportunity, and communities having a meaningful voice in decisions affecting their futures. These concerns are particularly visible across rural Texas, where Sims describes families struggling with healthcare access, rising living costs, and the expansion of large data centers.
As an information technology professional, Sims recognizes the economic benefits of technological development. But she also believes communities deserve protections for their water supplies, electricity costs, property values, and quality of life. Her position is not to reject progress, but to ensure that progress benefits the people expected to live with its consequences.
What Her Candidacy Means for Black America
For Black Americans, Sims’s candidacy represents another chapter in the long relationship between civil rights, political representation, and economic opportunity. Her grandmother helped secure national recognition of an important milestone in Black freedom.

Sims is now seeking a role in shaping the policies that determine how Americans experience that freedom. When I asked what her candidacy means for Black American communities, Sims offered a revealing perspective. “I think the greatest thing that I bring is years of experience in the Black voice because I am Black and female, but I think it’s more than the Black voice, it’s the people’s voice.”
Her response does not diminish the distinctive challenges facing Black Americans. Instead, it connects those challenges to broader concerns about economic mobility, access to resources, and representation. For Sims, strengthening Black communities includes expanding entrepreneurship, protecting educational opportunities, improving healthcare access, and ensuring that working families have a fair chance to prosper. “All of that wasn’t DEI. It was people,” she said while discussing programs designed to expand opportunity.
Her message suggests that the pursuit of equity and the pursuit of shared prosperity need not be competing ambitions.
Why This Race Matters Beyond Texas
Sims entered the Democratic primary with limited time to campaign, yet won approximately 60 percent of the vote. Now she faces a more formidable challenge against an established incumbent. The outcome will contribute to determining which party controls the U.S. House of Representatives.
But the broader significance lies in the questions her campaign raises about congressional accountability, civic participation, and whether elected officials remain connected to the communities they represent. “I am a humanitarian first and foremost,” Sims explained. “I am a person that believes that we are much stronger together than division causes us to be.” It is a philosophy that transcends Texas and speaks to a nation struggling to reconcile its differences while confronting shared challenges.
The Responsibility of the Next Generation
As our conversation concluded, Sims emphasized that democracy requires more than admiration for candidates or frustration with government. It requires participation. Her advice begins with getting people to the polls. Voters can confirm their registration, research candidates, make an early-voting plan, encourage others to participate, volunteer, or support campaigns through lawful contributions. Texas residents can find official voting information at VoteTexas.gov.
Perhaps the most powerful lesson of Sims’s candidacy is not whether she ultimately wins a seat in Congress. It is that a woman who helped her grandmother teach America to remember freedom is now challenging Americans to consider what they will do to protect it.

Ms. Opal Lee spent decades walking toward a more complete recognition of American history. Her granddaughter is pursuing a different path, guided by the same conviction that progress requires action. And it all began with three words that extend far beyond one congressional campaign. Why not you?
