- People over politics. This campaign is not about red versus blue—it’s about right versus wrong, truth versus harm, and putting everyday people back at the center of our democracy. That means accountability with integrity. Leadership means showing up, telling the truth, listening deeply, and answering to the people—not donors, not special interests, not party pressure.
- I’m seeking this office because I believe freedom has to show up in real life, not just in speeches, in whether one job can pay the bills, whether a family can afford healthcare, and whether our kids can dream without debt. I’ve spent my life building practical pathways through community work, workforce programs, and service rooted in faith. Now I’m ready to bring that same steady, solutions-first leadership to Congress and fight for living wages, strong public schools, and an economy that works for working people.
- Nearly 250 years ago, our nation was founded on the principle that no single person should hold unchecked power. The Constitution created three co-equal branches of government to protect the people, safeguard democracy, and prevent authoritarian rule.
Today, that balance is under strain. The erosion of congressional oversight and the weakening of checks and balances threaten the very system that has sustained our democracy for generations.
I am running because Congress must reclaim its constitutional role. We must restore accountability, defend the rule of law, and renew the true spirit of American democracy — not only for the people of Texas’ 25th District, but to strengthen our nation’s credibility and leadership around the world.

Campaign website
Sims' campaign website stated the following:
| “ |
Immigration What is your policy on immigration? My immigration policy is rooted in dignity, due process, and keeping families together. I support a roadmap to citizenship for long-time immigrants, including Dreamers and Temporary Protected Status (TPS) holders, along with safe, orderly border management. I support humane asylum processing, reforming work visa programs to prevent exploitation, and protecting workers so they can report wage theft and unsafe conditions without fear. Balance of Power How would you preserve the Constitution's checks and balances to keep the government accountable to the people? I will uphold the Constitution's separation of powers and defend Congress's oversight role. I will demand transparency, support strong ethics and anti-corruption laws, and oppose abuses of emergency powers that sidestep the public. I will protect an independent judiciary and fair, nonpartisan elections, because government must answer to the people, not special interests. Constitutional Rights What is your plan to ensure Constitutional rights are protected? My plan is to defend fundamental civil rights for everyone, without exceptions. I will protect voting rights, equal protection, free speech, and due process, and oppose policies that target people based on race, religion, or gender. I will strengthen enforcement of civil rights laws and demand real accountability for abuses of power, because our rights are the guardrails of democracy, and families must be able to trust the law will protect them. Economy & Affordability What is your plan to address affordability? My plan starts with a simple truth: affordability begins with a living wage. I will fight to raise pay, protect the right to organize, and crack down on wage theft so work actually covers the cost of life. I will lower everyday costs by taking on corporate price gouging, expanding affordable housing, and reducing health care and prescription drug costs. Affordability is the foundation of the American Dream, and the promise is that one job should be enough. Healthcare What steps would you take to ensure that healthcare is affordable and accessible for all Americans? I will fight to make health care affordable and accessible by strengthening the ACA, expanding Medicaid, and protecting coverage for preexisting conditions. I support lowering prescription drug costs by letting Medicare negotiate and taking on corporate price gouging. I will oppose policies that cut benefits or raise costs, and I will protect reproductive care. No family should delay care or go into debt just to stay healthy. |
