Both candidates are Republican and no Democrats qualified by Thursday's noon deadline.
That means, barring a major upset by a write-in candidate in the fall, the overall election will be more than likely determined during the Aug. 12 primary.
(The special general election will be Sept. 29, coinciding with the city of Knoxville primary.)
Haynes resigned from the West Knox County 14th District state Rep. seat in late May to serve as the state GOP chairman.
Here's a snapshot of the candidates:

She and her husband have been married for 30 years and have three children.
