IRON MOUNTAIN — All five Dickinson County Board incumbents are seeking reelection and all five will be challenged either in the Aug. 6 primary election or the Nov. 5 general election — or in some cases both.

Tuesday’s filing deadline for partisan offices in Michigan was met by a dozen candidates for Dickinson commissioner seats.

Candidates for all other Dickinson County offices are unopposed at this point. The deadline for candidates without party affiliation to file for the November ballot is July 18.

Dickinson County Sheriff Scott Rutter, a Democrat, will not seek reelection. The lone candidate is Aaron Rochon, the current undersheriff, who filed as a Republican.

The county board races are:

— District 1: Incumbent Joseph Stevens of Kingsford will be challenged in the Republican primary by Angela Olson.

— District 2: Incumbent Ann Martin of Iron Mountain will face Kevin Sullivan in the Republican primary. William J. Revord is unopposed in the Democratic primary.

— District 3: Incumbent Barbara Kramer of Iron Mountain is challenged in the Republican primary by Dan Harrington. Sandi Lefebvre is unopposed in the Democratic primary.

— District 4: Henry Wender of Breitung Township, the current board chairman, is opposed in the Republican primary by Peter Swanson.

— District 5: John Degenaer Jr. of Norway, an incumbent Democrat, will face Republican challenger Victoria Jakel.

Terms for county commissioners will be four years, up from two years. The change was made under state legislation that passed with bipartisan support in 2021, effective with the fall 2024 election.

Dickinson County officials unopposed for reelection to four-year terms, all Republicans, are Lisa Richards, prosecutor; Carol Bronzyk, clerk-register of deeds; Lorna Carey, treasurer; Michael Ghere, mine inspector; and Kevin Trevillian, drain commissioner.

Thomas D. Slagle, the incumbent probate judge, is unopposed for reelection to a six-year term.

Candidates who change their minds about running have until Friday to withdraw.

Any candidate who wants to seek a Republican or Democratic nomination with write-in votes must file a declaration of intent before primary voting begins.

In Iron County, only District 1’s Patti Peretto, a Democrat, has filed so far for reelection to the county board. Commissioners in other districts are serving without party affiliation.

Candidates for other Iron County offices are Amy Donati, county-clerk register of deeds, Democrat; Tom Karvala, mine inspector, Democrat; Chad DeRouin, prosecutor, Republican; Ryan Boehmke, sheriff, Democrat; and Melanie Camps, treasurer, Democrat. All are incumbents.
