This is the seat currently held by fellow Republican Marsha Abell. Abell says she will run for re-election.
Ungethiem is known in political circles for helping organize a group that opposed the city-county consolidation effort in 2012.
"What I found is going through the reorganization issues," said Ungethiem, "that I could see that the current office holders weren't really listening or paying attention to the views of the people."
The primary is set for May.
