Why they’re
Sensible
Katie Washnok is the energetic, community-rooted voice that District 3 needs in Pierre. Her leadership of the Brown County Republican Party and the Aberdeen Chamber of Commerce demonstrates she can build coalitions and deliver results, not just talk about them. She has been explicit that she wants District 3 to be "a priority in Pierre" and advocates for real infrastructure investment, job creation, and keeping families in South Dakota. Sensible South Dakota is drawn to her clear-eyed demand for "less talk and more action" and her record of earning recognition as one of the region's top young leaders.
Key positions
“I believe government works best when it's small, efficient, and accountable — with decisions made close to home.”
“Aberdeen and Northeastern South Dakota are ready for growth; we need leaders who are ready and able to advocate and make sure we are a priority in Pierre.”
“I am focused on real results: infrastructure, more jobs, and opportunities that keep families right here in South Dakota. It's time for less talk and more action, Aberdeen!”
“I am a commonsense conservative — pro-life, pro-business, and pro-Second Amendment.”
