About this race

Democrat Mark William Campbell won his party's June 2, 2026 primary outright with 457 votes (no opponent), per the county's official primary results; the seat is open (incumbent Republican Nathan Montgomery did not file for re-election, per the county's official Board of Supervisors roster). No Republican candidate filed. On the Republican primary ballot, write-in votes were scattered: the largest single named write-in total was 12 votes for a person recorded as "Mark Campbell," out of 19 total Republican write-in votes cast for the office (the balance went to other named write-ins, including 2 votes each for Keith Dencklau and Aaron Newell). This agent could not confirm from an official county document whether that write-in vote met Iowa's statutory threshold for nominating a candidate whose party fielded no filed candidate (Iowa Code section 43.66), whether "Mark Campbell" is the same person as Democratic nominee Mark William Campbell, or whether any Republican nominee was certified for this seat. No Republican candidate is listed here; Webster County's certified November 3, 2026 candidate list should be checked before publishing a Republican name.

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.
