With the filing deadline for candidates in the August primary election coming at noon Monday, only one incumbent Shawnee County elected official has an opponent.


Sheriff Brian Hill, a Republican, faces opposition for his seat from fellow Republican Tony Weingartner, the assistant director of the Kansas Bureau of Investigation.


But only the sitting incumbent has filed to run for the other five county elected offices.


Those are held by 2nd District County Commissioner Kevin Cook, a Democrat; 3rd District County Commissioner Aaron D. Mays, a Republican; County Treasurer Larry Mah, a Democrat; County Clerk Cynthia "Cyndi" Beck, a Republican; and Register of Deeds Becky Nioce, a Republican.


Candidates hoping to run in this year’s Aug. 4 primary in Shawnee County must file to run by noon Monday at election commissioner Andrew Howell’s office at 3420 S.W. Van Buren. The general elections will be Nov. 3.


The website for Howell’s office on Sunday listed 48 candidates — including 29 Republicans and 19 Democrats — as having filed to run for federal, state and county offices in Shawnee County.


That’s five fewer than the 53 who ran for those offices in the Aug. 2 primary during the last presidential election year, 2016.


Information posted on the website of Howell’s office indicates that in other races:


• Incumbent Republican Mike Kagay and Democrat Joshua Luttrell are the only candidates to have filed for the office Kagay holds as Shawnee County district attorney.

• Eight Republicans and two Democrats have filed to run for the U.S. Senate seat being vacated by retiring Sen. Pat Roberts. The Democrats are Barbara Bollier and Robert Leon Tillman.
