Democrats' ballots, however, were bare in the spring.
"When there's no candidate on a ballot, we look at the write-ins," Deputy Chief Clerk Jean Byers said.
McCarney and Gladhill "both petitioned to have their write-ins cumulated, meaning all the spellings are counted," she said.
Byers said incumbent Republican supervisor C. Stewart McCleaf did not, and, if he had, he would have had enough write-in votes to appear on Democratic ballots.
"He did not opt to do that," Byers said.
Democrats appear higher on ballots this general election due to state law concerning placement, which is based on the political party of the governor.
Gladhill, McCarney and Kulla all have been attending supervisors meetings regularly.
Gladhill, 50, of 14547 Carrosmar Road, Blue Ridge Summit, Pa., said she wants to see greater public involvement in the affairs of local government.
She is a retired correctional officer and currently works in business management. The lifetime township resident is a member of the One Mountain Foundation, Antietam Watershed Association and Washington Township Conservation Zoning Committee.
McCarney, 57, of 11 Eastland Circle, Waynesboro, said consideration should be given to how development progresses. McCarney, an engineer and self-described fiscal conservative, has lived in the township for 41 years.
Kulla, 43, of 11617 Woodlea Drive, Waynesboro, said he would look for ways to manage development without taking away the rights of property owners. A senior partner in a local law firm, he has lived in the township for 17 years and previously served on the Waynesboro Area School Board.
The general election is Nov. 6.
