A former Jefferson County commissioner will challenge Sheriff Jeff Herrig in the August Republican primary.

David Christy of Meriden, who served as a commissioner from 2005 to 2009 before he was defeated in a 2008 primary, filed to run against Herrig. Herrig, of Valley Falls, in 2008 took over for longtime Sheriff Roy Dunnaway when he retired.

Christy is a retired agent with the Kansas Bureau of Investigation.

According to the Jefferson County Clerk’s Office, Republicans Kyle G. Brown of Grantville and Wayne Ledbetter of Perry will also square off in the Aug. 7 primary election for the County Commission 2nd district seat because Dunnaway, who has served as a county commissioner since retiring as sheriff, did not file for re-election.

The other remaining incumbent county officials, all Republicans, do not have opponents. They are 3rd district Commissioner Richard Malm; County Clerk Linda M. Buttron; Treasurer Mary F. Underwood; Register of Deeds Delia Heston; and, County Attorney Jason Belveal.
