The Republican primary ballot for sheriff is expected to be composed of a number of hopefuls, now that incumbent Dennis Quakenbush is term-limited and not able to run for another term.

John Lowes, chief deputy of the Hamilton County Sheriff’s Office, has filed to run for Hamilton County sheriff in the upcoming Republican primary. Lowes, a career law enforcement officer with more than 28 years of experience, is seeking the office as Quakenbush prepares to conclude his second term in 2026.

Lowes currently oversees the day-to-day operations of the Sheriff’s Office and working with deputies and command staff on public safety efforts across the county. During his career, Lowes has held a variety of roles, including patrol, investigations, field training and administrative assignments.

In a statement announcing his candidacy, Lowes said he is running to provide experienced leadership and maintain public safety in Hamilton County.

“I am running for Sheriff because I believe Hamilton County deserves experienced conservative leadership that will protect our families, uphold the Constitution, and enforce the law fairly and firmly,” Lowes said. “Public safety requires vigilance, accountability, and a commitment to conservative principles that put the rule of law first.”

Lowes will appear on the Republican primary ballot in May.

Quakenbush has endorsed Lowes’ candidacy. In announcing his support, the sheriff cited Lowes’ experience and leadership within the department.

“John Lowes has served our community with integrity for more than two decades and has proven himself to be a capable and trusted leader,” Quakenbush said. “As Chief Deputy, he has played a central role in leading our department and ensuring we remain focused on transparency, accountability, and keeping Hamilton County safe.”

Lowes said he is grateful for the endorsement and emphasized continuity within the Sheriff’s Office.

“Dennis Quakenbush has led this department with professionalism and a clear focus on public safety,” Lowes said. “I am honored by his support and committed to building on the strong foundation that has been established to keep Hamilton County safe.”
