Former State Treasurer Dennis McKinney is running for the Kansas House, where he served before holding statewide office.
McKinney has filed as the only Democrat running in the 117th House District of southwestern Kansas, which includes his hometown of Greensburg.
He served in the House from 1992 to 2008, including as minority leader. He was then appointed by the governor to fill a vacancy in the state treasurer's office but lost his bid for a full, four-year term in 2010.
Three Republican newcomers are also running in the 117th District. They are John Ewy, of Jetmore; Mitchell Rucker, of Burdett; and John Unruh, of Haviland.
There's no incumbent because of the way three federal judges redrew the state's political boundaries to account for population changes over the past decade.
