About this race

Open seat (incumbent Tom Broeker's term ends in 2026 and he did not file for reelection). Republican Brian Thie, who won a three-way Republican primary (1,358 votes, 53.72%) over Eric Gerst and Nick Baker, faces Democrat Bob Bartles, who ran unopposed in his party's primary (2,062 votes, 99.23%), per the county's official primary election results and candidate list.

What this office does

County commissioner. The county board is the county's legislative and, in most states, executive body. Commissioners adopt the county budget and property tax rate, oversee roads, the jail, public health, planning and zoning in unincorporated areas, and appoint or confirm department heads. In counties with an elected county executive or judge, the board's role is mainly the budget and ordinances.

This list comes from official election records but may be incomplete. It can miss, for example, late or petition candidates and some city, school and district races. Your official sample ballot is the final word.
