From Glen Flora, Wisconsin, Edming graduated from Flambeau High School in Tony, Wisconsin, in 1964. He earned a teaching certificate from the Taylor County Teacher's College in 1967 and attended various other University of Wisconsin System institutions, but did not receive another degree.[2]
He became an entrepreneur and, in 1972, became the owner of Edming Oil Company, a gas station and convenience store.[3] He went on, in 1974, to become the owner of Edming Manufacturing Co., a livestock feed and farm supply company.[4] In the 1980s, he founded OvenWorks Pizza, a manufacturer of frozen pizzas.[5]
He served on the Rusk County Board of Supervisors from 1978 to 1988, and served on the Rusk County Hospital Board from 1980 to 1982, and again from 2010 to 2018.[6]
In 2014, he entered the race for Wisconsin State Assembly in the 87th district following the announcement that six-term incumbent Mary Williams would retire at the end of that term.[7] The Republican primary was extremely close, a recount ordered by the Wisconsin Government Accountability Board found Edming the winner by a mere 17 votes over his primary opponent Michael Bub.[8] Edming went on to win the general election with 66% of the vote.[9] He was subsequently reelected in 2016, 2018, 2020 and 2022.[2]
