Following-up on his announcement in late January that he intended to run in the June 5th Primary on the Republican ticket, Atlantic resident John. P. Hartkopf, Thursday, filed his completed nomination papers with the Cass County Auditor’s Office.

Hartkopf is officially running for the County Board of Supervisors in District 3. The seat became available when current District 3 Supervisor Mark Wedemeyer announced in January, that he would not be running for re-election.

Two other candidates have already filed for the same seat. Hartkopf faces a challenge during the Primary from fellow Republicans Linda Templeman, and Dana Halder.
