Conservative leader and working family advocate David Casteel has officially announced his candidacy for the Missouri State Senate in Jefferson County, vowing to bring principled leadership, more fiscal responsibility, and a commitment to protecting Missouri values. With Senator Mary Elizabeth Coleman not running for re-election, Casteel is seeking to win the open Republican primary in August 2026.
“As a lifelong Missourian, I believe our state needs strong, conservative leadership that prioritizes lower taxes, job growth, and personal freedoms,” said Casteel. “I am running for State Senate to be a voice for blue collar workers, small businesses, and the traditional values that make Missouri great.”
Casteel, the founder of Gutter Pros, has been a tireless advocate for economic growth, parental rights in education, and Second Amendment protections. His platform priorities include:
- Lowering Taxes & Cutting Wasteful Spending – Casteel is committed to reducing the tax burden on Missouri families and small businesses while ensuring that government remains efficient and accountable.
- Defending Conservative Values – A strong advocate for faith, family, and freedom, he will stand against government overreach and policies that threaten Missouri’s way of life.
- Supporting Law Enforcement & Public Safety – Casteel will continue to ensure law enforcement is fully funded, strengthen laws against violent crime and illegal immigration, and support first responders.
- Protecting Parental Rights in Education – He believes parents should have a say in their children’s education and will push for policies that remove political propaganda in the classroom, while increasing teacher pay to recruit and retain quality educators.
- Standing Up for the Second Amendment – As a strong supporter of the right to bear arms, Casteel will fight against any attempts to infringe on gun ownership and the right to self-defense.
Casteel’s campaign is focusing on grassroots engagement, meeting directly with voters across the district to listen to their concerns and advocate for policies that reflect their values.
“Jefferson County deserves a leader who will fight for ‘We the People’ — our freedoms, wallets, and the conservative values that define our way of life. That’s my mission for the state senate.”
